For 30 years, China Carbon Molecular Sieve Co., Ltd. specializes in the production of carbon molecular sieves (CMS) with various pore sizes for gas separation applications. These CMS products are specifically designed for use in nitrogen generators and other Pressure Swing Adsorption (PSA) gas generators.

The company achieves the desired separation performance by carefully controlling the micropore diameter of the carbon molecular sieves and selecting suitable raw materials during the manufacturing process. By customizing the pore size distribution of the CMS, they can optimize the adsorption and desorption properties to effectively separate different types of gases.

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) adjusting micropore 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.

Micro pore diameter distribution and micro pore diameter adjustment are the key steps in the preparation of carbon molecular sieve. We control the pore size of CMS which is suitable for separating all kinds of gases.

For example, for O2/N2 gas separation, the pore size diameter of our carbon molecular sieve(CMS) for nitrogen is 0.30nm. For CO2/CH4 gas separation, the pore size diameter of our carbon molecular sieve(CMS) for methane is 0.35nm. For N2/CH4 gas separation, the pore size diameter of our carbon molecular sieve(CMS) for methane is 0.35nm.

China Carbon Molecular Sieve Co., Ltd. is not only an old manufacturer of molecular sieve and carbon molecular sieve but also provides high-quality products. The company can provide carbon molecular sieve(CMS) for nitrogen and carbon molecular sieve for CH4 with low air consumption and energy-saving characteristics. These CMS products have been the favorable option for PSA generators. The PSA generators are energy-efficient by using carbon molecular sieve for nitrogen and carbon molecular sieve for methane. Our carbon molecular sieve for nitrogen and carbon molecular sieve for CH4 have been exported to a number of countries and regions in Asia, America, and Europe. Our objective is: "classic quality, classic services." We strive to provide the best services for our clients at home and abroad.

When the micro pore diameter distribution of carbon molecular sieve and Lithium molecular sieve are uniform and their micro pore diameter is between the two kinds of gas and close to the mixed gas in the pore, they are suitable for separation.
