5 angstrom molecular sieve

5A Molecular Sieve is calcium-type A aluminosilicate crystal. It can adsorb molecules with critical diameter no larger than 5Å. All molecules adsorbed by 3A and 4A molecular sieve can also be adsorbed by 5A. It separates normal alkanes from branched & cyclic hydrocarbons and is widely used for PSA hydrogen production and n/iso-paraffin separation.
