    Carbon Molecular Sieve CMS220

    Carbon molecular sieve is a type of carbonized chemical substance,not a material made of carbon.The component of its raw material is mainly phenolic resin.

    Its internal special pore structure can effectively separate oxygen and nitrogen molecules, while possessing strong oxygen molecule adsorption ability, making them an ideal adsorbent for pressure swing adsorption (PSA) nitrogen generation.

    Product Work Principle

    Carbon molecular sieve contains a large number of micropores with 3.0 angstrom aperture, which is exactly between the diameters of oxygen and nitrogen molecules (2.9 angstrom for oxygen molecule and 3.1 angstrom for nitrogen molecules). In the process of of nitrogen generation, when compressed air flows through the adsorption bed composed by carbon molecular sieve, oxygen molecules can pass through the micropores of carbon molecular sieve and diffused into its wall, while the entering of nitrogen molecules are restricted and discharged from the top of adsorption vessels,thereby achieving nitrogen gas enrichment.


    Product Production Procedure

    The production of carbon molecular sieve mainly includes five procedures: grinding, extrusion, carbonization, activation, and pore formation. Throughout the entire production process, carbonization and pore formation are the key to the production process. The adsorption and separation of oxygen and nitrogen of the product mainly depend on the carbonization and pore forming techniques, respectively.

    Huzhou Boda Chemical Technology Co., Ltd. has over 20 years of production experience. We adopt the most advanced activation and pore forming technology, and our carbon molecular sieve is well-known in the industry for its strong adsorption performance and stable nitrogen production rate.

    Product Supporting Equipment

    The reactor used for carbon molecular sieve nitrogen generation is called pressure swing adsorption (PSA) nitrogen generator and also known as nitrogen reactor.

    PSA nitrogen generator is generally equipped with two adsorption towers (Tower A and Tower B) equipped with carbon molecular sieves. During the nitrogen production process, the carbon molecular sieves in one tower are in the oxygen adsorption process, while the carbon molecular sieves in the other tower are in the oxygen desorption process. The carbon molecular sieves in Tower A are alternately adsorbed by the carbon molecular sieves in Tower B, thus achieving continuous nitrogen production.
