?Carbon molecular sieve based on coal or organic compounds as raw materials for the molecular diameter made of porous carbon material. Let's us see carbon molecular sieve of the development history.

? Carbon molecular sieve seventies of the 20th century developed a new type of adsorbent, is a good non-polar carbon materials. Twentieth century, the fifties, along with the tide of the Industrial Revolution, carbon materials, more and more widely, Application areas in which activated carbon with a carbon molecular sieve PSA Nitrogen PSA Nitrogen with Carbon molecular sieve.
