Columnar activated carbon is made of high-quality coal, coconut shells, and sawdust, and is processed through a series of production processes. It has the appearance of black cylindrical particles and is widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, nitrogen generators, air separation equipment, paint shops and other fields.
Activated carbon is an adsorbent, catalyst and catalytic carrier. Each of its functions has a wide range of applications in industry. In terms of adsorption, it can adsorb various vapor substances, and it can also adsorb various substances in solution. Of course, activated carbon is best at adsorbing organic matter, and it is much worse for inorganic matter. So some people call activated carbon a universal adsorbent. Although this statement is somewhat exaggerated, it is true. The catalytic properties of activated carbon make it widely used in industry.
Activated carbon is often used as a catalyst carrier in the chemical industry, and the catalytic active components are deposited on the surface of activated carbon by impregnation. Activated carbon not only plays the role of carrier in the catalytic process, because its pore structure characteristics, specific surface area and chemical properties will have a significant impact on the activity, selectivity and service life of the catalyst, so as a carrier it cannot be replaced by any other porous material.
Pellet activated carbon is suitable for water purification, decolorization, protection, solvent recovery, VOCs treatment, waste gas treatment, carrier catalysis, air purification, desulphurization and other industrial production and living applications etc.
