PSA nitrogen specific activated carbon is made from high-quality coal and coconut shell as raw materials, and is processed through crushing, grinding, mixing, molding, carbonization, and activation. It has the characteristics of high mechanical strength, regular shape, uniform particle size, large specific surface area, and less surface dust. It also has appropriate numbers of large, medium, and micro pores, fast adsorption speed, and low bed resistance. Suitable for direct deoxygenation of inert gases such as nitrogen, argon, helium, carbon monoxide, and carbon dioxide, widely used in nitrogen purification equipment and air separation nitrogen production equipment, and particularly suitable for post purification and oil absorption in pressure swing adsorption nitrogen production.

The importance of the placement of activated carbon in the nitrogen production system: The activated carbon filter in the nitrogen production system should be placed in front of the air buffer tank after the third stage filtration. This placement is very scientific and necessary. If placed after the air buffer tank and before the nitrogen generator, without buffering by the air buffer tank, a large amount of compressed air cannot be processed instantly. Activated carbon filters require the use of a tank for filling, resulting in a much larger amount of activated carbon filling compared to activated carbon filters. This ensures the protective effect of activated carbon on the molecular sieve.
