It especially has the co-adsorption effect of carbon dioxide and water, hydrogen sulfide and water. It is the best desiccant for gas, chemical and air separation industries. All technical indicators that can be adsorbed on type 3A, 4A, and 5A molecular sieves can be adsorbed by type 13X.
Gas purification in air separation units, removal of water and carbon dioxide, drying of natural gas, liquefied petroleum gas, liquid hydrocarbons and desulfurization of general gas deep drying.

Applications
Mainly used for gas drying and purification, purification of raw gas in air separation units (while removing H2O and CO2), desulfurization of liquid hydrocarbons and natural gases (removal of hydrogen sulfide and mercaptans), catalyst supports. Drying of pharmaceutical and air compression systems, general gas deep drying. It is also used to desulfurize gasoline, which can reduce the sulfur content in high-sulfur gasoline from 0.003 to about 0.0003.
