13X Molecular Sieve is a sodium-based aluminosilicate with a large pore size of approximately 10 angstroms, offering very high adsorption capacity for moisture and larger molecules. Its wide pore structure allows it to adsorb compounds such as carbon dioxide, hydrogen sulphide, mercaptans, and various organic vapours, making it particularly effective for air separation and gas refining processes.

The product exhibits fast adsorption kinetics, high capacity, and excellent regeneration performance. Supplied in 4×8 mesh, 13X Molecular Sieve is optimised for low pressure drop and reliable operation in high-flow PSA and gas purification systems.
