Impregnated activated carbon is made from granular/cylindrical/powdered activated carbon with high adsorption performance, impregnated with alkaline solutions such as potassium hydroxide and sodium hydroxide, and then refined by high-temperature drying. This kind of activated carbon is widely used to remove organic gases and vapors from air or other gas streams, such as hydrogen sulfide, sulfur dioxide, etc.

Impregnated activated carbon has a large specific surface area and suitable pore structure, can withstand high temperature and high pressure, is not easily broken, is easy to regenerate, and has a long service life. It not only performs well in liquid phase adsorption and air purification, but also plays an important role in the purification, separation and refining of chemical raw material gases, pharmaceutical industry gases, carbon dioxide gas for beverages, hydrogen, chlorine and other gases. In addition, impregnated activated carbon is also widely used in fields such as hydrogen sulfide gas removal and oxidation gas adsorption in PTA devices.

Compared with ordinary activated carbon, impregnated activated carbon has significant differences in terms of material, production process, scope of use and performance. Impregnated activated carbon is obtained by special impregnation treatment of ordinary activated carbon. Its raw materials are the same as ordinary activated carbon, but after special treatment, it has a higher specific surface area and better catalytic performance. In terms of production process, impregnated activated carbon needs to undergo multiple impregnation treatments, such as impregnating active oxides or active substances, and performing heat treatment and other processes, thereby adding more adsorbates and catalysts, further improving the adsorption effect and catalytic performance. Therefore, impregnated activated carbon is superior to ordinary activated carbon in terms of adsorption performance and catalytic performance. It can more effectively absorb and remove harmful substances, such as formaldehyde, benzene, ammonia, sulfur dioxide, etc., and catalyze the decomposition of harmful gases and reduce the emission of harmful substances.
