  • Product overview


5A molecular sieve is a chemical substance, the molecular formula is 3/4CaO·1/4Na2O·Al2O3·2SiO2·9/2H2O. Molecular Sieve Wholesale

5A molecular sieve can adsorb any molecules smaller than the pore size, and is generally called calcium molecular sieve. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, ethyl chloride, ethyl bromide, butanol, etc., and can be used in normal isohydrocarbon separation, pressure swing adsorption separation and water Co-adsorption with carbon dioxide.

The main purpose

This kind of sieve absorbs substances at the molecular level. It can absorb up to 22% of its body weight. The adsorption principle is similar to that of chromatography, except that the molecular combination of the substance is not changed.

1. Natural gas drying, desulfurization, and carbon dioxide removal;

2. Separation of nitrogen and oxygen, separation of nitrogen and hydrogen to produce oxygen, nitrogen and hydrogen;

3. Petroleum dewaxing, separation of normal hydrocarbons from branched hydrocarbons and cyclic hydrocarbons.
