                                                           Activated carbonCAS No.                 :  64365-11-3EINECS No.           :  264-846-4Molecular Formula :   CHS number             :  3802.1000                         1-Columnar/Pellet/Cylinder activated carbon                  Product introduction:This product selects high-quality raw coal as raw material, adds a certain proportion of adhesive, cocatalyst, etc., and produces high-quality activated carbon through kneading, high-pressure molding, carbonization, activation and other processes. It has the characteristics of large specific surface area, high mechanical strength, large adsorption capacity, fast adsorption speed, long service life, and is not easy to break and de-powder under the action of high temperature, high pressure and water immersion. It is widely used in solvent recovery, catalyst carrier, deep purification treatment of hazardous waste gas, paint booth waste gas, electronic factory waste gas, benzene, sulfur and other hazardous substances.Product features:Due to the use of high-quality sawdust and coconut shell as raw materials, the columnar activated carbon made from it has lower ash content, less impurities, gas adsorption value and CTC than the traditional coal-based columnar carbon.Cylindrical carbon process:Columnar activated carbon is generally made of powdered raw materials and binders through kneading, extrusion molding, carbonization, and other processes. It has developed pore structure, good adsorption performance, high mechanical strength, easy to regenerate repeatedly and low cost; It is used for the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery, soil improvement, etc.Precautions for Columnar activated carbonNot all columnar activated carbons can absorb harmful gases. Only when the pore structure of columnar activated carbons is slightly larger than the diameter of harmful gas molecules, can harmful gas molecules enter completely (neither too large nor too small), can the best adsorption effect be achieved. At present, there are mainly bamboo charcoal and black gold charcoal handicrafts on the market. The price of black gold charcoal is extremely expensive, and the iodine adsorption index is only about 650 mg/g; The iodine adsorption index of bamboo charcoal products is only about 700 mg/g. Compared with similar products on the market, our modified columnar activated carbon has good adsorption effect and high cost performance.SpecificationItem ParameterItem ParameterIodine Adsorption Value (mg/g)800-1200Strength  %90-95 Specific surface area m2/g 850-1300  Methylene blue value mg/g120-150 Total pore volume cm3/g0.8 min Formaldehyde adsorption rate %  60-100Filling density g/cm30.35-0.55 Diameter  mm1.5-8 PH 7-11 Moisture  %   5Ash  % 10Carbon tetrachloride absorption  % 40-90 Product introduction:Coal-based granular activated carbon is refined with high-quality anthracite as raw material and advanced technology. Its appearance is black amorphous particles.Product features:Due to the use of high-quality anthracite as raw material, the columnar or broken granular activated carbon has the absolute advantages of low ash content, less impurities, gas phase adsorption value and CTC.Coal-based granular activated carbon process:Cylindrical coal-based granular activated carbon, also known as coal-based carbon, is generally made of powdery raw materials and binders through kneading, extrusion molding, carbonization, activation and other processes. It can also be extruded with powdered coal columnar activated carbon and binder. It has developed pore structure, good adsorption performance, high mechanical strength, easy to regenerate repeatedly and low cost; It is used for the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery.Characteristics of coal-based granular activated carbon:Coal-based granular activated carbon is a kind of porous carbon-containing material. Its highly developed pore structure makes it have a huge surface area, so it is easy to fully contact with toxic and harmful gases (harmful impurities) in the air. This highly developed pore structure - capillary tube constitutes a strong adsorption force field. Thus, the unique adsorption performance of coal columnar activated carbon is endowed. When these toxic and harmful gases (impurities) touch the capillary tube, the strong adsorption field around the coal columnar activated carbon hole will immediately suck the toxic and harmful gas (impurities) molecules into the hole to purify the air.SpecificationItem Standard Item Standard Iodine value mg/g min 1000  Strength  %92 min Specific surface area m2/g min 850Methylene blue value mg/g120-150Total pore volume cm3/g min 0.8 Residual chlorine adsorption rate % min 85 Filling density g/cm30.35-0.55 Size diameter  mm 1.5-8PH 7-11 Moisture  %   6Ash  % 10Carbon tetrachloride absorption  % 40-90
