5A Molecular Sieve
·
Description: A kind of alkali-metallic, silicon-aluminum compounds,
It could absorb the molecular which critical diameter is not more than 5
angstroms.
·
Applications:Used for the dehydration and purification of various
hydrocarbon and non-hydrocarbon gas and liquid streams. It is used for the
separation of straight and branched chain hydrocarbons, sweetening and drying
of natural gases and the production of high purity hydrogen.
