Carbon molecular sieve is a new adsorbent developed in 1970s. It is a non-polar carbon material. Carbon molecular sieves are used to separate air enrich nitrogen at room temperature. Compared with the traditional low-temperature high-pressure nitrogen production process, the low-pressure nitrogen production process has the advantages of less investment cost, faster nitrogen production lower nitrogen cost. Therefore, it is a nitrogen rich adsorbent for PSA air separation in engineering. This nitrogen is used in the chemical industry, oil gas industry, electronics industry, food industry, coal industry, pharmaceutical industry, cable industry, metals, is widely used in heat treatment, transportation storage.
Molecular sieves are synthetic chemicals with network structure. It can separate molecules with different shapes diameters, molecules with different polarity, molecules with different boiling points molecules with different saturations, which has the function of "screening" molecules, so it is called molecular sieves. At present, molecular sieves are widely used in metallurgy, chemical industry, electronics, petrochemical, natural gas other industries. There are mainly 3a, 5A, 11x, carbon molecular sieve packing molecular sieve (the main component of packing molecular sieve is alumina, which is implanted as catalyst).
Carbon molecular sieve is a kind of excellent non-polar carbon material. Its main component is elemental carbon its appearance is black columnar solid. Because it contains a large number of micropores with a diameter of 4 angstroms, these micropores have strong instantaneous affinity for oxygen molecules can be used to separate oxygen nitrogen air. In industry, nitrogen is produced by pressure swing adsorption device. Xintao carbon molecular sieve has the advantages of large amount of nitrogen production, high nitrogen recovery rate long service life. It is suitable for all kinds of PSA nitrogen generator, is the choice of PSA nitrogen generator.
In nature, there is pure carbon. For example, diamonds are very pure carbon, pure oxygen, diamonds actually burn turn into carbon dioxide. Diamonds are the hardest thing. People use it to cut glass install it on the drill bit of a drilling machine. A pioneer who goes underground. But, after all, there are many diamonds that cannot meet industrial demand. At present, China has successfully made diamond graphite graphite under high temperature high pressure.
