Properties:
Pressure swing adsorption (PSA) silica gel appears as transparent or translucent spherical particles with a chemical formula of mSiO₂·nH₂O. It is chemically stable, non-toxic, and odorless. It shares similarities with narrow pore silica gel, but exhibits superior selective adsorption capabilities. Its primary characteristics are rapid adsorption and desorption.
Applications:
Pressure swing adsorption (PSA) is a high-tech gas separation and purification technology. PSA silica gel is primarily used for the recovery, separation, and purification of carbon dioxide gas. It is used in the production of carbon dioxide in the ammonia synthesis industry and food and beverage processing. It can also be used for drying, moisture-proofing, and dehydration and purification of organic products.
