Zhulin Granular Coal based activated carbon is made from coal though high temperature activation. It is black in appearance, with large pores. It is applied to solvent recovery, catalyst carriers, gas adsorption and water purification in the field of chemicals, environmental protection, power plant, electronics, petrochemical industry, farming, medicine, marine transportation.
Coal based activated carbon originates from coal that has undergone a steam activation process Coal based carbon has mainly mesopores and macropores and is very popular in gas phase purification portable water purification wastewater purification and aquariumpond water purification applications The carbonaceous product of wood Applications Gas phase purification Water purification system
Our Powder activated carbon is manufactured using pure pine wood which is an excellent base for manufacturing activated carbons with good adsorption power. The steam activated process is done by activating the charcoal in a rotary kiln by heating at high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCl / H2SO4) and purified water. This results in reduction of ash content to as low as 1% and iron as low as 50 ppm. The gradation of different qualities of activated carbon is done on the basis of Methylene blue value and iodine value. The iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. We can relate the iodine value of activated carbon directly to its surface area because of the above fact.
Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water. Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size. Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements
Using well-selected Datong bituminous coal and strictly-controlled steam activation. The carbons have the following performance: high internal surface area,optimised pore size, developed transport pore, high hardness, high blue number. All of which makes it more suitable for liqued phase application. The direct granular activated carbon can be processed into different size (4-325mesh) upon the request of customer.
made by high quality Anthracite coal, through the selection, powder and screen process, it has good shape, high hardness, anti-pressing and wearing, does not dissolve in acidic, alkaline, neutral water and it is popularly used in various water. The main usage is as water media during water treatments, which can soften the water and improve the taste.
Coal activated carbon 25kg/bag, or 500kg/bag
Activated carbon which used water filtration Coal Activated Carbon series has been made of the worldwide superior anthracite. We follow strict as well as scientific formulation, and they have features of high hardness, low ash, high void age, a large surface area, and so on. They are widely used in water purification, wastewater disposal, air purification, solvent recycling, medical treatment, and many more. Activated carbon granules are usually used infiltration. Activated carbon filtration is among the many processes used in water treatment. The activated carbon removes the contaminants that include organic materials, and since it can easily be able to remove the odor-causing pollutants, it does make the drinking water more palatable.
Coal Based Activated Carbon Coal based activated carbon originates from coal that has undergone a steam activation process. During activation, millions of pores are created on the surface of the carbon, increasing the total surface area. Coal based carbon has mainly meso-pores and macro-pores and is very popular in gas phase purification, potable water purification, wastewater purification and aquarium/pond water purification applications.
The coal based powder activated carbon is made of high quality anthracite coal as raw material; by special production process (first carbonization and activation, then grinding into powder) is refined. This product is the appearance of black powder, are not dissolved under the general solution. Odorless, has a flocculation effect and filtration effects and large surface area, adsorption ability, high purity, filter fast, quality stable.
