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
