Carbon molecular sieve is a new type of adsorbent that has developed in the seventies of the twentieth century, and is a non-polar carbon plant raw material, and CarbonMolecularSieves (CMS) is used to extract vapor agglomeration N2, and adopts the production process of low nitrogen inhibition at room temperature, which has the advantages of less investment project consumption, faster nitrogen production rate and low N2 cost than the traditional hydrogen production process. Therefore, it is the current pressure swing adsorption (collectively referred to as P.S.A) air separation nitrogen-rich adsorbents in the building circle, this kind of N2 is widely used in chemical plants, industrial production of petrochemical equipment, electronics industry, biological industry, coal industry, pharmaceutical industry, cable industry, metal surface solution, transportation and storage.

Carbon molecular sieve is to apply the selected characteristics to ensure the purpose of extracting CO2 and N2. When the molecular sieve sucks sediment gas, the pores and vertical pores only have the role of outlets, and the molecular structure of the adsorption is transported to the micropores and submicropores, and the micropores and submicropores are counted as the volume that really plays the role of adsorption.

Therefore, in the production and processing of carbon molecular sieve, according to the specifications of the molecular structure specification, the internal micropores of the carbon molecular sieve should be {{0}}.28~0.38nm. Within the range of microporous specifications, CO2 can quickly diffuse into the bore according to the microporous branch, while N2 cannot follow the microporous branch, so as to ensure oxygen and nitrogen extraction.

If the diameter is too large, CO2 and N2 molecular sieves are easy to enter the micropores and cannot play the role of extraction, while the diameter is too small, CO2 and N2 cannot enter the micropores and cannot play the role of extraction

At present, there is not much difference in the appearance of carbon molecular sieves produced by most manufacturers, so customers can not distinguish whether they are imported molecular sieves or Chinese molecular sieves only by observing the appearance of molecular sieves. However, if the manufacturer claims to be using high-quality imported molecular sieves when purchasing machinery and equipment, but the price is far lower than the market price, then you need to be careful. If you buy without selling, it is unlikely that machinery and equipment manufacturers will not be able to sell machinery and equipment without profits. It is not terrible to buy the machinery and equipment of Chinese molecular sieve, but it is not terrible to buy back Chinese molecular sieve at the price of imported molecular sieve, and the harm can increase
