Active clay CS-1055 - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| What is activated clay? | activated clay is a highly active adsorbent which is processed by bentonite as raw material. It is widely used in the decolorization of oil industry. Activated Clay has a strong adsorption capacity for pigments in oils, especially chlorophyll and other colloidal impurities, and has a stronger adsorption capacity for basic radicals and polar radicals. After the oil is decolorized by white clay, a small amount of earth odor will remain, which can be removed in the deodorization process. activated clay has the characteristics of strong adsorption capacity, low oil carrying rate, high activity, easy precipitation and filtration, low acid branch and low acid recovery rate. The product is widely used in petrochemical, pharmaceutical, Oil Chemical, animal and vegetable oil decolorization and purification, and can effectively remove the edible vegetable oil pigment, tetracycline, and odor. As a decolorizing agent, it is also widely used in soap, plastic, resin, food, paint, detergent, brewing and other industrial production. As an adsorbent, it is also widely used in the removal process of organic phosphorus, organic sulfur, aflatoxin and other harmful substances. It can also make the olefin polymerization into advanced lubricating oil, radioactive sewage treatment also has a good effect. |
| composition | active clay is mainly composed of silicon dioxide (SiO2), aluminum oxide (Al2O3), iron oxide (Fe2O3), calcium oxide (CaO), magnesium oxide (MgO), etc. |
| Main properties | The main properties and uses of activated clay are: 1, has a wide range of decolorization and purification, has a good adsorption and decolorization effect in the application of oil decolorization process, has a strong adsorption of pigments and impurities, the decolorization rate of various pigments in vegetable oil reached 85 ~ 95% 2, with specific adsorption, can remove all kinds of deep pigment and impurities, such as chlorophyll, lutein and carotene, the color of the oil after decolorization and purification is light, clear and bright, and has good stability and low acid value. 3. It has the ability to adsorb and remove aflatoxin and benzo (a) pyrene in oil. 4, activated clay as a processing aid in the adsorption of the pigment, impurities and harmful substances, after strict filtration and oil completely separated, the filtration technology and control means are mature technology in China. 5, activated Clay has a certain shelf life, generally 12 months. Although the expired activated clay will not affect the quality of the oil, it will adsorb a certain amount of moisture in the air, so that the decolorization force decreases and the oil loss increases, which leads to the increase of production and processing costs. |
| production process | The main production methods of activated clay with bentonite as raw material are full wet method, full dry method and semi wet method. The traditional all-wet method is to mix bentonite, sulfuric acid and water, and then heat to 100 ℃ with stirring for activation for a period of time. After washing, drying and crushing, the product can be obtained. The biggest disadvantage of this method is that the amount of acid consumption is large, which leads to large water consumption, serious environmental pollution and high cost. The traditional all-dry production process is to mix a small amount of sulfuric acid and water with bentonite, and then stir them thoroughly, place them for a period of time, and then dry them. Although this method reduces the amount of acid, no waste water discharge and other environmental pollution, but its product quality is low, greatly limiting its use. The semi-wet production process is to mix a small amount of sulfuric acid and water with bentonite, then fully stir, activate (place) at a certain temperature for a period of time, and then add acid and water for the second step of activation. Semi-wet production process is a better solution to the problems of all wet and dry process, simple process, low cost, high product quality. In general, the acid consumption of the semi-wet production process is reduced by half to 2/3 (1/2~2/3) compared with the traditional process, water consumption is also reduced by 1/2~2/3, less waste water, a little treatment that no environmental pollution, low cost, in the same case, the product quality than the traditional method of decolorization power increased by 30%. |
| Application in oil refining and decolorization | activated Clay has a strong selective adsorption of pigment, under certain conditions, the pigment and other impurities in the oil are adsorbed, so as to achieve the purpose of decolorization. The oil treated by adsorbent not only achieves the purpose of improving oil color and removing colloid, but also can effectively remove some trace metal ions in oil and some substances that can cause poisoning of hydrogenation catalyst, so as to provide good conditions for the further refinement of oil. activated clay has become the most widely used decolorizing agent for edible oils due to its large specific surface area, strong adsorption capacity, low activity, and no chemical interaction with oils and other chemicals, the amount of white clay added in the decolorization process is determined according to the color of oil and the requirement standard for refined oil. For example, the internal control standard for small packaging oil is higher than the requirement standard for the color of sold bulk oil, the amount of clay used in the decolorization process is also slightly more. General use of decolorization of oil weight 2%-5%. The more the clay was added, the better the decolorization effect was. However, the addition of too much clay will also decrease the yield of refined oil, because the clay will adsorb some oil and fat while adsorbing pigment, which increases the refining consumption and cost, general refining workshop waste clay oil content is generally 20%-25%. At present, a few enterprises use leaching method to separate the oil from the activated waste clay, but the separated oil is black in color due to the effect of clay, and cannot decolorize to a good color. Therefore, the oil content of waste clay is taken as an important index for the choice of activated clay manufacturers by domestic oil refining manufacturers. |
| Application | used for decoloration of animal oil, vegetable oil, mineral oil and refining of petroleum products, also used as organic synthesis catalyst can be used for animal and vegetable oil decolorization, filter aid and adsorbent, catalyst and catalyst carrier mainly used for petroleum processing products (lubricating oil, paraffin, Vaseline). For all kinds of mineral oil, edible vegetable oil, animal oil, solid paraffin, fatty acid, ethanol and benzene, and gas, liquid drying and dehydration. Used as a catalyst in the chemical industry and powder pesticide filler. Used in coal mine dust explosion, radioactive pollutants removal and radioactive waste treatment. |
| production method | sulfuric acid method bentonite is dried to a surface moisture of 8-20%, and then screened, add full swelling and pulverization in the activator with 80 ° C. Hot water, and then add a quantitative amount of concentrated sulfuric acid, so that the sulfuric acid concentration is controlled at 10%-15%, under the pressure of 0.2 Mpa activation 2~3H. Then use the pressure inside the container to send the materials to the acid tank to separate the unreacted sulfuric acid and fine slurry materials. The remaining granular materials are washed with water, filtered and dried at 100~200 ℃, the water content in the material was less than 8%, and then crushed until the 200 mesh screen passed more than 90% to prepare the activated clay product. |
