Carbon molecular sieve is a new soebent mainly used in the PSA N2 gas generator based on its air separative capacity.

Nitrogen generation by Pressure Swing Adsorption(PSA) process is a technology used to separate nitrogen from a mixture of gases under pressure according to the special selective adsorption characteristic of the Carbon Molecular Sieve(CMS).

Quality Indicator of the CMS:

1. the diameter of the CMS granule 1.7-1.8mm

2. the period of adsorption 120S

3. the bulk density 680~700g/L

4. the compressive strength≥95N/granule

5. the performance of the CMS as following:

Model	Pressure	Purity	Output	Recovery ratio
		99.9	135	33
	0.6	99.5	220	41
CMS-220		99	330	44
		99.9	145	30
	0.8	99.5	252	41
		99	370	47
