Two major components to edit the main component of carbon molecular sieves for elemental carbon, the appearance of black columnar solid. For containing a large number of microporous molecular sieve having a diameter of 4 Ed, the micropores of the instant molecular sieve oxygen molecules strong affinity properties, may be used to separate oxygen and nitrogen in the air by pressure swing adsorption apparatus (PSA) Preparation of nitrogen industrially. Xin Tao large carbon molecular sieve nitrogen, nitrogen recovery, long life, suitable for various types of PSA Nitrogen, Nitrogen PSA is the product of choice. Carbon molecular sieve nitrogen air separation has been widely used in chemical, metal heat treatment, electronics manufacturing, food preservation, oil and other industries. [1] In the manufacture of carbon molecular sieves, zeolite molecular size depending on the size of oxygen, carbon molecular sieves inside the pore distribution should be 0.28 ~ 0.38nm. Within this pore size range, the oxygen can quickly diffuse into the hole through the porous openings, and the nitrogen is difficult through the porous opening, so as to achieve an oxygen, nitrogen separation. Microporous carbon molecular sieve pore size separation of oxygen, nitrogen-based nature of the molecular sieve, if the pore size is too large, oxygen, nitrogen, into the pores of the molecular sieve is easy, but there is no separation of the role; pore size is too small, oxygen, nitrogen are can not enter the micropores, but there is no separation. [1] The company sieve, zeolite, there are new new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new molecular sieves, and you hand in hand into the brilliant, for a better future!
