Features:

1) A carbon molecular sieve belongs to carbon sorbent. It is a carbon material 

    with many hollow holes in its structure. Its hole-structure is irregular. CMS is

    one kind of non-metering compound and its main performance is based on 

    the micro-hole structure. 

2) The air separation capacity of CMS relies on the different speeds of diffusion 

    of gas passing CMS micro-hole and/or different adsorbabilities

3) Under balanced condition, the adsorption amount of CMS to oxygen and

    nitrogen is very close, while the speed of oxygen molecule passing through 

    the micro-hole structure is much faster than the speed of nitrogen molecule

4) This principle is the base of CMS nitrogen generation. At the moment far 

    before the balanced condition occurs, using PSA process flow, nitrogen is

    separated out form air
