Production processes, product performance Fullers Earth and the main performance characteristics

The characteristics of the treated oil decolorizing clay:

1, less loss of oil, pure taste, color reaches gb. Deodorant cleaning out the oil decolorization, the slag ratio is less than using the old methods of wash oil slag rate. The refined diesel color not only reduction, and placed the longer, its color instead of the more clear, more bright, very clear. The taste is pure oil.

2, low cost, wide range of application. Because the slag is less, so the cost is reduced correspondingly. The agent can not only wash with crude oil refining the small refinery, can handle the lubricating oil, vacuum first, second oil, waste oil refining diesel and for the old ways can not wash out the oil, suitable for a wide range of.

3, labor saving, time saving, labor saving, greatly improve the cleaning work rate, without heating, pressurizing, convenient operation. With oil decolorization in addition to taste agent than the old way of improving the efficiency of 2-3 times, greatly saves time, and solves the problem of wash oil cold old methods do not separate, can be long-term production.

4, to solve the problem of waste treatment, using waste residue, the elution is not bonded, non caking, no solidification, waste reuse. If the sales, than the waste old way to wash out more money, solve the problem of environmental protection.

Fullers Earth

In the edible and non edible oils and fats in the industrial production of bleaching earth, so-called used to remove from crude oil and fat colored and colorless pigment. Purification of the process of the adsorption attempt, oil and fat color and stability may substantially increase. Bleaching earth different types may be used to purify. The first group is composed of a high performance bleaching clay called (HPBE) formation. Strong mineral acids in HPBE by boiling temperature about the acid under leaching bentonite production. In order to obtain high performance bleaching earth, concentrated acid typically used to dry the starting clay matter basis of about 60 to 90 weight%. In the filtration of aluminum ions at the same time, other metal ions from the clay structure and the acid dissolved away. After the filter is formed in the activation period of salts, the acid must be separated from the products of clay by filtration, and the residual acid must be removed from the clay through sufficient washing. If the residual acid high level has been left in clay, quality of the bleached oil weakened. High level of residual acid adverse acid from fatty acid triglycerides in the oil free fat. During the acid leaching of clay, clay and residues from waste containing ionic salts. Such waste liquid must be by precipitation or further such as sewage treatment method to neutralize.

Advantages of the new type of Fullers Earth with high bleaching activity, which may be through the use of acid surface treatment has been further strengthened, for example by spraying acid solution to the clay material. Because of its high bleaching bleaching earth activated only a small amount of added to the oil to purify the purification degree required. In addition to the high efficiency of bleaching, bleaching clay is suitable for massive application should also provide high filtration efficiency and high capacity efficiency. High filtration efficiency of bleaching in a reasonable time period after the oil filter is very important. High efficiency of the remaining oil holding loss minimization in bleaching clay used in the oil is very important. In order to get the optimal bleaching earth, these three qualifications must meet all. Activated bleaching efficiency, filtration efficiency and capacity efficiency can be merged into bleaching clay allows evaluation of the total efficiency. Suitable for bleaching earth mass bleaching oil should therefore form a high total efficiency.

Production status of activated clay, and on how to deal with

Activated clay is a clay (mainly bentonite) as raw material, the inorganic acid, followed by water rinsing, drying adsorbent made of, look for the milky white powder, odorless, tasteless, non-toxic, strong adsorption, can adsorb colored material, organic matter. Easy to absorb moisture in the air, place too long will reduce the adsorption properties. However, heating above to 300 ℃ began to lose water of crystallization, the structure changes, effects of fading effect. Activated clay is insoluble in water, organic solvents and oils, almost completely soluble in hot caustic soda and hydrochloric acid, the relative density of 2.3-2.5, in water and oil swelling minima.

Activated clay China manufacturer about 40, annual output of about 420000 tons. Device for producing ability is 50000 t/a. Activated clay production mainly concentrated in the northeast, North China, East China, production accounted for over 70% of the country.

Activated Clay

Raw material

In the past people only know of bentonite used as activated clay raw material, actually otherwise, mineral soil with clay properties can be used as the raw material of activated clay. Hunan recently made by sepiolite activated clay, Zhejiang also found that b axis disordered kaolinite can also produce activated clay, Shandong successfully developed with water purifying agent residue as raw material of activated clay. Thus, active clay raw materials more widely. But the activated clay we usually refers to the activated clay with bentonite as raw material.

Bentonite ore grinding to a certain size, can thoroughly and acid activated bentonite mining ground water, high, soft without drying, using direct high-speed beating or wet ball milling, low power consumption.

The deep excavation of the bentonite, as hard as a stone, not dispersed in water, wet beating or cost is much higher than that of wet milling, drying and Raymond mill. The water in the < 20% conditions, to focus on the improvement of drying and milling equipment. Raw material moisture activated clay is less than 15% will be able to use. Adsorption of water only removed 5% of the milling process. The hot flue gases into the Raymond mill, the production cost is much lower than the wet mill.

Manufacturing method of activated clay

Activated clay production process of bentonite as raw material are all wet, dry, semi wet, vapor phase method, calcination etc.. The conventional wet is bentonite, sulfuric acid, water after mixing in the case of mixing heated to 100 ℃, the activation of a period of time after washing, drying, crushing to obtain the product. Disadvantages of this method is the largest consumption of acid, resulting in washing water consumption, serious environmental pollution, high cost. Dry the traditional production process is a small amount of sulfuric acid and water and bentonite mixture and stir well, for a period of time, then drying, grinding to obtain the product. Although this method reduces the consumption of acid, no waste water discharge, the pollution of the environment, but the quality of the products is low, which greatly limits its use. The production process and semi wet is a small amount of sulfuric acid and water and bentonite mixture and stir well, activated under certain temperature (placed) for a period of time, then adding acid and water and then a second step activation. The production technology of semi wet method can solve some problems of the wet and dry, simple process, low cost, high product quality. Generally speaking, the production technology of semi wet than the traditional process of acid consumption is reduced by 1 / 2-2 / 3, water consumption is reduced by 1 / 2-2 / 3, less waste water, a treatment that is no environmental pollution, low cost, under the same conditions, the quality of the products increased by 30% compared with the traditional method for decoloring capacity. Vapor phase technique in pressure thermal vapor to water, acids, soil and dry mix, between static by vapor phase, liquid phase, solid phase was acidified reacted furiously to form semi dry granular acidification, a kind of new technologies by rinsing processes for preparation of activated clay. The technical advantages of the existing legal system of dry and wet clay and calcination method of activated white clay production technology as a whole, has a good practical value, provides a new technology for activated clay produced in china. The technology and traditional wet preparation of activated clay process has the following advantages: compared with acid and water consumption were reduced by about 50%, the production cycle is shortened 1 / 2-1 / 3; light pollution, and easy to control; covers an area of small, high utilization rate of equipment, less investment, quick effect, and in close connection with the existing wet process process and equipment. According to different processes, activated clay can be aluminum, silicon and aluminum sulfate white sodium sulfate, gypsum etc..

China bentonite Professional Committee of the expert group to Kong Bingyan on activated clay production process and equipment optimization optimization scheme, this scheme satisfies the quality of produced competitive products; investment; mechanical equipment operation and repair cost is low; environmental protection. In short production to lower cost.

The production process of activated clay has three problems to be solved: (1) there are certain selectivity to the original bentonite, not all of the different types of bentonite can produce efficient the decolouring ratio ≥ 90%, or some type of bentonite could produce ordinary activated bleaching earths rate greater than 80% – 85% or semi activated clay. Activity index is still not up to H (high activity of activated clay) on the activity of requirements. So the range of its use are subject to some limitations. (2) treatment of acidic wastewater, the lime dosage is too large. (3) oil absorption rate. The decolouring capacity of heavy oil 2% – 5%. The oil was decolorized with clay, inevitably entrained oil, entrainment is activated clay was 20% – 50%, thereby increasing the coke consumption and cost. At present, a few enterprises by leaching is separated from the active waste clay in oil, but after the separation of the oil from clay, color is black, not decolouring good color. Therefore, domestic oil bleaching department wants to use oil absorption of activated clay small.

Application of activated clay

In the range of application, active clay than the surface area, the adsorption capacity, the decolorizing efficiency is high, and the activity degree is low, do not react chemically with the grease and other chemical substances. For the filtration rate of decolorization of liquid quickly, the residual liquid rate is low, such as edible oil, sugar decolorization decolorization. Edible oil bleaching products used for the decolorization of all kinds of vegetable oil, animal oil and mineral oil, such as soybean oil, rapeseed oil, peanut oil, cottonseed oil, sunflower oil, palm oil, etc.. Sugar decoloring agent products with rich majorite purification refined sugar, its colour and lustre, reducing sugar content, pH, ion content, thionyl chloride ion content, protein content, sugar boiling temperature and calcium and magnesium ions content reached the current standard, save the decolorization treatment costs about 60%. Environmental odor absorbing agent has good adsorption odor, odor can eliminate the refrigerator, pet bedroom, toilet and other places. After bleaching liquid is transparent and clear, stable quality, no smell. After using the product, after proper treatment can be used for the two time, it will not cause environmental pollution. Also can be used for moisture desiccant, internal medicine alkali antidote, vitamin A, B adsorption agent, lubricating oil contact contact agent, the gasoline vapor refining agent, as well as the raw material in the temperature of polymerization catalyst, high temperature polymerization agent and manufacturing of particulate clay. In addition, active clay can also be used for carbonless copy paper chromogenic agent.

Activated clay is another important use is the preparation of particulate clay.

Particulate clay is the activated clay as the main raw materials by chemical processing and become, the appearance of unshaped granular activated clay, it has higher specific surface area, has a very high adsorption capacity, widely used in petrochemical industry, aviation kerosene refining, aromatics extraction, mineral oil, animal and vegetable oil, wax and organic liquid decoloration refining, but also for refined oil, base oil, diesel oil, residual olefins, glial, Li Qing, and other impurities removing basic nitrogen compounds.

Clay particles can also be used as a moisture desiccant, internal medicine alkali antidote, vitamin A, B adsorption agent, lubricating oil contact contact agent, the gasoline vapor refining agent, can also be used as a temperature of polymerization catalyst, high temperature polymerization agent.

At present, non-toxic, no entrainment, oil absorption rate is small, can be used for edible oil decoloration refining and not in the petroleum catalysis reaction medium discoloration caused by particulate clay is hot demand.

At present, China clay particles mainly Ling’an Fulong adsorbent factory several manufacturers in the production, mainly non water resistant clay particles, decolorizing capacity, good activity, can basically meet the domestic needs of aromatic industries.

Used for clay particles and petrochemical industry aromatic stock must be activated clay produced by traditional process, dry process production or use attapulgite compound cannot meet the requirements of production.

Details of the use of bentonite

Bentonite is widely used:

1 casting industry

Casting bentonite is the largest user of bentonite, the annual amount of 1100000 tons.

Bentonite used in casting is mainly applied to the clay bonded sand, because bentonite has strong adhesion, high plasticity, good air permeability characteristics of stripping, stable physical and chemical properties, such as high temperature and wet conditions. Clay bonded sand for molding material production casting process, this is a long history, thriving in a variety of chemical bonded sand today, clay wet sand is still the most important molding material, its applicable scope, consumption of large, is any other material can not be compared to. High pressure molding, injection molding, molding, static modeling and non shock pressure vacuum process modeling in modern times, also is to use the clay wet sand as the premise, the ability to adapt to the other conditions of the clay wet sand strong. Casting bentonite mainly sodium bentonite and calcium sodium bentonite two, sodium bentonite is made from natural sodium bentonite or artificial Na bentonite processing, with its good reusability and the wet compression strength is high and the foundry industry are welcome. Because of good plasticity, can prevent the scab, scab, dropping block, sand mold collapse, and the molding cavity strong, high strength, convenient metal industry casting wet or dry mold, sand binder precision casting is preferred. Calcium sodium bentonite from natural calcium base bentonite processing, is widely used in light of casting sand binder. The utility and sand casting convenient and popular with users. Compared with other binder, bentonite has an important characteristic, is that it has certain heat capacity. As long as the heating temperature is not too high, the removal of free water bentonite as long as water, still can restore the adhesive ability. Binding capacity of bentonite in water can be manifested only after. Bentonite lose the binding ability, also with its dehydration. So far, that of bentonite in the water has three forms: a water free water, granular bentonite adsorbed water, heated to 100 ℃, can remove free water, removing free water bentonite, adhesive ability was not affected by the two kinds of water is strong; combined with water, long time heating at 110 ℃, bentonite can be removed completely free water, but does not remove firmly bound water. Has been completely removing free water bentonite, then at a higher temperature (200 ℃, 300 ℃) heating will continue to lose weight, there is still water loss. Bentonite by heating after dehydration, just add water, can completely recover bonding ability; three kinds of water is crystal water, also known as the structure of water. The lattice water to some or all removed only in high temperature. Lattice water removing swelling water, that the loss of binding capacity, become dead clay. Different bentonite, loss of binding capacity of different temperature. By differential thermal analysis experiments show that: Generally speaking, the failure temperature natural sodium bentonite is 638 ℃, calcium bentonite is 316 ℃. Artificial activation of Na bentonite, due to the activation of different conditions, the temperature is not a failure, but lower than the natural sodium bentonite.

2 drilling mud

Bentonite for drilling mud is bentonite second users, the annual amount of 700000 tons.

Bentonite is a kind of clay mineral with montmorillonite as main component, has strong water absorbability, can absorb the equivalent of 8 times the volume of the water itself, the volume expansion of 10 ~ 30 times, was suspended and colloidal state in aqueous solution. In oil, gas drilling work, want to use mud to cool the drill bit, remove debris, protect wall and equilibrium pressure. Bentonite dispersivity, grout amount is large, so it is ideal material for manufacturing drilling mud. As drilling mud bentonite, the most important requirement is the suspension properties, wet sieve analysis and moisture content.

Bentonite

The important effect of bentonite in drilling, makes its use very large. It is understood, the average recovery wells, about the use of bentonite 8 tons.

3 iron ore pellet

Iron ore pellet bentonite is bentonite third users, the annual amount of 450000 tons.

Activated clay principles, characteristics and production technology

Our senior activated clay products, select high-quality raw materials, the introduction of foreign advanced production technology and production process carefully. Products are white, pink or white powder or granular, non-toxic and tasteless, insoluble in water, easy to absorb moisture; with larger specific surface area and more active acid center, so the catalytic and adsorptive ability strong, so not only have better decolorization ability, at the same time, a high degree of activity, the low rate of oil, filtering speed, is the most ideal bleaching agent.

Use of  Activated Clay  widely, in animal and vegetable oil refining industry for the decolorization and purification; in the petroleum industry, used for petroleum resin, wax, paraffin oil, kerosene decolorization and purification; paper industry for paper dyes, dye, fill oil. As a fire extinguisher powder in forestry and water and soil conservation, binder hond elimination of oil in water; used as a catalyst and catalyst carrier in chemical industry, carrier insecticides, pesticides and fungicides, rubber and plastic filler, desiccant and filtering agent, adsorbent radioactive waste; in water purification and sewage treatment as absorbent and flocculant.

Odorless, tasteless, non-toxic white or beige powder or granule. A scattered, greasy feeling. Insoluble in water, organic solvent and all kinds of oils and fats. Almost completely soluble in hot caustic soda solution.

Method for producing active clay of the popular process all dry, semi wet, vapor phase method, through the comparison, the production process of the practical analysis found that need to be solved in current activated clay production process and the following three problems:

1, to deal with the problem of acid waste water, the lime dosage is too large;

Question 2, oil absorption rate, the decolouring capacity of heavy oil 2%-5%. The oil was decolorized with clay, inevitably entrained oil, entrainment is generally active clay content 20%-50%, thereby increasing the coke consumption and cost. At present, a few enterprises by leaching is separated from the active waste clay in oil, but after the separation of the oil from clay, color is black, not decolouring good color. Therefore, domestic oil bleaching departments hope oil absorption of activated clay small;

3, the original bentonite have certain selectivity, not all can be produced efficiently the decolouring rate greater than 90% for all the different types of bentonite, or some type of bentonite could produce ordinary the decolouring ratio ≥ 80-85% or semi efficient active clay. Activity index is still not up to H (high activity of activated clay) on the activity of requirements. So the range of its use are subject to some limitations;

Introduces bleaching clay, performance and formation process

Bleaching clay is also called “bentonite”, “bleaching earth”, dominated by smectite group minerals. Common minerals include feldspar, gypsum, calcite, quartz and the incomplete decomposition of volcano tuff material. General pink, white, yellowish, grayish green color. The appearance of colloidal, low hardness, immersed in water to swell, no plastic, low refractoriness. Often the tuff or volcano rock in sea water or groundwater, by weathering in alkaline medium (pH=7-8.5) environment of deposition. Because it has strong absorbency and water swelling, so use in petrochemical fields, such as used in petroleum, oil, sugar, wine making, paper making, textile and other industries as a purifying agent and bleaching agent.

Bleaching clay mineral filter is always a tricky and long-term unsolved problems. Slurry by ultrafine grinding, grading and bleaching, must pay the economic price. If the filtering problem can not be solved well, not only directly affect the enterprise efficiency, waste of mineral resources, but also polluted water and environment phenomenon is very serious

Bleaching Clay

Clay is mainly composed of aluminous rocks, such as feldspar, pegmatite granite, porphyry, gneiss through long-term weathering, and often through the water transport and deposition, is a variety of fine mineral mixed body, its main chemical composition is SiO2, Al2O3 and crystal water. With the geological formation conditions are different, also contain a small amount of alkali metal oxide, alkaline earth metal oxide and metal oxides.

Most of the literature on clay will start to define or clay to some professional terminology to explain, this is very necessary, because the varieties and usage of clay is indeed much. Often the clay was classified according to Mineralogy, geology, chemical composition, physical properties of the cause or industrial purposes.

There are 3 ways: 1. The formation of clay minerals is related to weathering. Types and medium weathered rock conditions such as water, climate, landform, vegetation and time factors determine the mineral species and save or not. Hydrothermal and hot spring water in rock, can form the clay mineral alteration zone. ③ by sedimentation, diagenesis mineral formation clay. In modern or ancient sediments can sometimes be formed with industrial significance of kaolin, bentonite, palygorskite, sepiolite clay and clay rock.

Use of kaolin is mainly used for ceramic raw materials, papermaking filler and coating; mainly consisting of montmorillonite bentonite used as drilling mud, binder catalyst oil refining and bleaching agent, iron ore pellet and casting sand binder; palygorskite and sepiolite clay is the manufacture of salt mud quality raw materials, grease decoloring agent and absorbent.

The use of Activated Bleaching Earth, characteristics, production processes and packaging

The white and pink, odorless and tasteless, non-toxic, good activity, strong adsorption, easy to absorb moisture in the air, such as placing too long or moisture will reduce its adsorption function, the use of appropriate heating (80 to 100 degrees) resurrection, if heated to 300 degrees above began to lose water of crystallization the structure, change, influence the bleaching effect

Activated Bleaching Earth product quality to meet the actual needs of users, can not just look at the sales contract index. For example: the filtration rate, oil rate, specific surface area, light stability, acid value of oil peroxide value, alkali nitrogen and other indicators, not making up the quality standard of the existing. The ore will be tested with laboratory data, and big difference is very big. Can not be used as the basis to build factories, geographical environment and social relationships, to detailed examination. Then, list the various process flow. It selects the best plan, to achieve high-quality, high yield, low consumption, safety objective.
