What is Carbon Molecular Sieve (CMS)

Carbon molecular sieves are a new type of adsorbent developed in the 1970s, which is an excellent non-polar carbon material. Carbon molecular sieves (CMS) are to separate air and enrich nitrogen gas.

They adopt a normal temperature and low pressure nitrogen production process, which has the advantages of low investment cost, fast nitrogen production rate, and low nitrogen cost compared to traditional cryogenic and high-pressure nitrogen production processes.

Therefore, it is the preferred pressure swing adsorption (P.S.A.) air separation nitrogen rich adsorbent in the engineering industry. This nitrogen is widely in various fields such as chemical industry, oil and gas industry, electronics industry, food industry, coal industry, pharmaceutical industry, cable industry, metal heat treatment, transportation and storage.

Carbon molecular sieve for PSA nitrogen production
In the 1950s, with the tide of the Industrial Revolution, the application of carbon materials became increasingly widespread. Among them,

the application field of activated carbon expanded the fastest in PSA nitrogen production using carbon molecular sieves, gradually developing from filtering impurities to separating different components.

At the same time, with the advancement of technology, human beings’ ability to process materials is becoming stronger and stronger. In this situation, carbon molecular sieves have emerged.

Main components

Main components
The main component of carbon molecular sieve is elemental carbon, which appears as a black columnar solid. Due to the presence of a large number of micropores with a diameter of 4 angstroms,

these micropores have a strong instantaneous affinity for oxygen molecules and can be to separate oxygen and nitrogen in the air. In industry, nitrogen is produced using pressure swing adsorption (PSA) devices.

Carbon molecular sieve has a large nitrogen production capacity, high nitrogen recovery rate, and long service life.

It is suitable for various types of pressure swing adsorption nitrogen generators and is the preferred product for pressure swing adsorption nitrogen generators.

Carbon molecular sieve air separation for nitrogen production has been widely used in industries such as petrochemicals, metal heat treatment, electronic manufacturing, and food preservation.
