Product Introduction

Impregnated activated carbon is made of coal-based granular activated carbon with high adsorption performance as raw material, impregnated with alkaline solutions such as potassium hydroxide and sodium hydroxide, and then refined by 130°-180° burning and drying. It is widely used to remove organic gases and steam in air or other airflows, such as hydrogen sulfide, sulfur dioxide, etc. Liquid phase adsorption, air purification. 

 

In water treatment applications, silver impregnated carbon also provides anti-microbial effects and is a perfect choice for earth-bound compounds. In air treatment applications, it is often used for hydrogen sulfide (H2S) removal in biogas plants, pump stations or anaerobic or septic tanks at wastewater treatment plants. For industrial exhaust or flue gas applications, activated carbon can be impregnated to target acid gases, ammonia, amines, aldehydes, hydrogen fluoride, mercury, arsine or phosphine.

 

The impregnation process is performed following the normal direct activation or agglomeration process, where the chemical is normally an acid, strong base or a salt, such as phosphoric acid, sodium hydroxide, calcium chloride or zinc chloride at temperatures up to 600 degrees C.

 

Impregnated activated carbon has a large specific surface area, suitable pore structure, high structural strength, can withstand high temperature and high pressure, is not easy to break, easy to regenerate, and has a long service life. It is widely used in the purification of chemical raw material gas, chemical synthesis gas, gas for the pharmaceutical industry, carbon dioxide gas for beverages and hydrogen, chlorine, hydrogen chloride, ethylene, acetylene, cracking gas, inert gas, etc., and the purification, separation and refining of exhaust gas from atomic facilities, hydrogen sulfide gas removal, PTA device oxidation gas adsorption, etc.
