An R & D background editing sieve market fifties of the twentieth century, along with the industrial revolution, the tide of molecular sieve adsorption, more extensive use of carbon materials, including applications of activated carbon with carbon molecular sieve nitrogen PSA PSA PSA nitrogen with carbon molecular sieve nitrogen with carbon molecular sieve zeolite extend the fastest production from the initial filter impurities evolved to separate different components. At the same time, as technology advances, the human processing capacity of the material is also growing, in this case, carbon molecular sieve emerged. [1] 3 working principle is the use of carbon molecular sieves, sieving editing features to achieve the separation of oxygen, nitrogen purpose. When molecular sieve adsorption of impurity gases, mesopores and macropores function as channels only, the molecules are adsorbed and transported to the sub-micropores in the zeolite pores, micropores and sub-micropores is the volume that really Adsorption. As shown below, the carbon molecular sieves comprise a large number of internal pores, the pores allow the kinetics of small molecules rapidly diffuse into the hole size, while limiting the entry of large diameter molecules. Due to the different sizes of the gas molecules relative diffusion rate differences, components of the gas mixture can be effectively separated. _ _ Molecular sieve zeolite molecular sieves by new Shanghai there are new molecular sieve 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!
