Separation of normal paraffin's from branched-chain and cyclic hydrocarbons, removal of H2S, CO2 and mercaptans from natural gas
5A Molecular Sieve
It is mainly applied to separate isomerism alkane,Meanwhile, it can also absorb the molecular which can pass through in 3A and 4A Molecular Sieve and whose diameter are less than five angstrom. Expecially the result is very evident in the changing pressure absorption system.
