Molecular sieve 5A is an alkali aluminosilicate carbon available in the form of Type A crystal structure with the pore size 5A or 5 angstroms. They have the tendency to absorb the molecules with the pore size smaller than 3A and 4A. It cannot adsorb the molecules with the diameter greater than 5A such as ISO compounds and all kinds of 4-carbon rings.
Such type of molecular sieve is widely used for the purification and separation of natural gas. Type 5A is generally used for separating the normal and isomerous alkane, for adsorbing moisture, humidity and carbon dioxide as well as for adsorbing pressure swing for gases. They can also be used for checking the exact composition through large volume density, water content, strength, and several other chemical specifications. It can be available in the form of sieve beads and molecular sieve pellets form.
