Columnar activated carbon coal, coconut shell, and wood chips are used as raw materials, and are refined through a series of production processes. Appearance is black cylindrical particles, widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, air separation equipment, painting workshop and other fields.

Columnar activated carbon is used in all aspects of industrial and agricultural production, such as alkali-free deodorization (refined desulfurization) in the petrochemical industry, ethylene desalination (refined fillers), catalyst supports (palladium, platinum, rhodium, etc.), water purification and sewage treatment; electric power Water treatment and protection of power plants in the industry; chemical catalysts and carriers, gas purification, solvent recovery and decolorization and refining of oils and fats in the chemical industry; refining and decolorization of beverages, alcohol, monosodium glutamate mother liquor and food in the food industry; gold in the gold industry Extraction, tail liquid recovery; sewage treatment, waste gas and harmful gas treatment, gas purification in the environmental protection industry; and cigarette filters, wood floor moisture-proof, odor-absorbing, automobile gasoline evaporation pollution control, preparation of various impregnating agent solutions in related industries Wait. Activated carbon will have good development prospects and a broad sales market in the future.

Columnar activated carbon has a good adsorption effect on volatile organic compounds in water, and the removal rate of various volatile organic compounds in water can reach 25% to 65%. Comparing the adsorption laws of various organic compounds with different molecular weights, it can be seen that for volatile organic compounds, the higher the molecular weight, the higher their removal rate. This is similar to the adsorption law of phenol and cationic bright yellow, that is, for small molecular organic matter in water, the larger the molecular weight, the easier it is to be adsorbed by activated carbon.

Columnar activated carbon mainly includes coal-based columnar activated carbon and wood columnar activated carbon (wood includes coconut shell and wood).

Wooden columnar activated carbon uses sawdust, coconut shell, etc. as raw materials, and the columnar activated carbon made by crushing, mixing, extrusion, molding, drying, carbonization and activation is lower than the traditional coal-based columnar carbon. Ash content, less impurities, CTC is dominant . Mainly used for 1. Gas phase adsorption 2. Recovery of organic solvents (benzene gas toluene, xylene, acetone recovery in acetate fiber industry, recovery of CS2 in viscose staple fiber production, etc.) 3. Removal of impurities and harmful gases, This technology has reached a very good level in China. Ordinary 4mm activated carbon, the adsorption of CTC is only 60%, not more than 70%, while the produced 4mm wood columnar activated carbon has a CTC adsorption rate of 100%, making up for the domestic shortage of CTC adsorption rate, reaching the international standard. Standard! Completely replace imported products. Coal-based columnar activated carbon uses anthracite as raw material and is refined and processed by advanced technology. Toxic gas purification, waste gas treatment, industrial and domestic water purification treatment, solvent recovery, etc.
