impregnated activated carbon It is selected with high adsorption performance Granular activated carbon from coal As raw material, it is impregnated with alkaline solution such as potassium hydroxide, and then cremated and dried at 130 ° - 180 ° Activated carbon Widely used to remove air or steam, Such as hydrogen sulfide, sulfur dioxide, etc.
Liquid phase adsorption, air purification, coal impregnated activated carbon products have a large specific surface area, suitable pore structure, high mechanical strength, can withstand high temperature, high pressure, not easily broken, long service life and other characteristics, and are widely used in chemical raw gas, chemical synthetic gas, gas for pharmaceutical industry, carbon dioxide gas and hydrogen for beverages, ethylene, acetylene, Purification of cracking gas and inert gas, purification, separation and refining of atomic facility exhaust, removal of hydrogen sulfide gas, adsorption of oxidation gas in PTA unit, etc.
