Over 30 years,China Carbon Molecular Sieve Co.,Ltd.manufactures different micropore diameter carbon molecular sieves(CMS) which is suitable for separating all kinds of gases by using phenolic resin and coconut shell as raw materials and controlling carbon molecular sieves micropore size which be used in nitrogen generators and other PSA gases generators.


  We use phenolic resin and coconut shell as raw materials to manufacture carbon molecular sieve(CMS)for nitrogen and carbon molecular sieve for CH4(methane).The preparation method includes four steps: 1) crushing, pretreatment, molding and drying of carbonaceous materials; 2) carbonization of formed products in inert atmosphere; 3) activation; 4) micropore diameter adjustment.
When the micropore diameter distribution of carbon molecular sieve are(CMS) uniform and their micropore diameter diameter is between the two kinds of gas and is close to the molecular diameter of the component to be separated, the diffusion rate or adsorption rate of the mixed gas in the pore is different, so as to realize the gas separation.
micropore diameter distribution and micropore diameter adjustment are the key step in the preparation of carbon molecular sieve.we control the pore size of CMS which is suitable for separation all kinds of gases.
To O2/N2 gas separation,The pore size diameter of our carbon molecular sieve(CMS) for separation nitrogen is 0.34nm to be used nitrogen generator .
To CO2/CH4 gas separation, The pore size diameter of our carbon molecular sieve(CMS) for separation CH4(methane) is 0.33nm to be used other PSA generators. 
To N2/CH4 gas separation The pore size diameter of our carbon molecular sieve(CMS) for separation CH4(methane) is 0.36nm to be used other PSA generators.
China Carbon Molecular Sieve Co., Ltd. is not only the largest manufacturer of molecular sieve,carbon molecular sieve but also Its molecular sieve,carbon molecular sieve are the high quality.China Carbon Molecular Sieve Co., Ltd.can provide with low air consumption and saving-energy of carbon molecular sieve(CMS)for nitrogen and carbon molecular sieve for CH4(methane).
Over 30 years, our carbon molecular sieve for nitrogen and carbon molecular sieve for CH4  have been the first and favorable option for PSA generator. The PSA generator are energy conservation by using carbon molecular sieve for nitrogen and carbon molecular sieve for separation CH4.
Our carbon molecular sieve for separation nitrogen and carbon molecular sieve(CMS) for separation CH4(methane) have been exported to a number of countries and regions in Asia, America and Europe. Our objective is: "classic quality, classic services." It strive to provide the best services for our clients at home and abroa.
