4A Molecular Sieve

4A Molecular Sieve

Introduction: 4A molecular sieve is a kind of potassium-sodium aluminosilicate with LTA-type skeleton structure which is composed of silicon-oxygen and aluminum-oxygen tetrahedrons.The main crystal hole of the 4A molecular sieve is an eight-membered ring structure, and the crystal pore size is 4Å (0.4nm).It can adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene, but does not adsorb any molecule with diameter greater than
