Columnar activated carbon is finely processed through a series of production processes and appears as cylindrical particles. It is divided into coal based columnar activated carbon, wood based columnar activated carbon, and coconut shell columnar activated carbon. Columnar activated carbon has a developed pore structure, good adsorption performance, large surface area, light weight, strong adsorption capacity, good wear resistance, high mechanical strength, and long service life. It can adsorb various VOC organic waste gases such as benzene, toluene, ketones, alcohols, tetrahydrofuran, dichloromethane, trichloromethane, trichloroethylene, vinyl chloride, carbon disulfide, formyl, gasoline, and fluorinated hydrocarbons.
Columnar activated carbon has the advantages of well-developed pore structure, large specific area, strong adsorption capacity, high mechanical strength, low bed resistance, good chemical stability, easy regeneration, and durability. Due to the reasonable pore size distribution of the product, it achieves significant adsorption and desorption, thereby greatly improving the service life of the product (average 2-3 years), which is 1.4 times that of ordinary activated carbon.
The production process of columnar activated carbon first requires grinding the raw materials to a certain fineness (usually above 95% through 0.08mm), adding appropriate binders (commonly coal tar) and water, and kneading and extruding them into carbon strips at a certain temperature; After drying, the charcoal strips are carbonized and activated to form columnar activated carbon. Columnar activated carbon products sometimes require acid washing, impregnation, modification and other treatments according to market requirements to meet customer adsorption needs.
Columnar activated carbon is widely used for exhaust gas purification, chemical raw material gas, chemical synthesis gas, pharmaceutical industry gas, beverage carbon dioxide gas, hydrogen, nitrogen, hydrogen chloride, ethane gas purification, gas purification and separation, atomic facility exhaust gas, etc. There are also impregnated columnar activated carbons, such as KOH activated carbon, NaOH activated carbon, sulfur impregnated activated carbon, desulfurization activated carbon, acid washed activated carbon, etc., used to remove special harmful gases.
