5A molecular sieve

5AMS

Type has a pore size that is 5A. It cannot adsorb any molecules smaller than 5A. This molecular sieve is an alkali alumino silicate in the calcium form of Type A crystal structure. The basic application is separation of the normal and isomerous alkane, co-adsorption of carbon dioxide and moisture, along with pressure swing adsorption (PSA) for gases. The sequence rate of adsorption is C3-C14, C2H5CL, C2H5Br, CH3L, C2H5NH2, CH2CL2CH2Br2, CHF2CL, CHF3, CF4, (CH3)NH2, B2H6CF2CL2, CHFCL2, and CF3CL.

Product Details

Features
