The 3A molecular sieve provided by our company refers to potassium A-type aluminosilicate. The 3A molecular sieve can adsorb molecules with a critical diameter not greater than 3A. It is commonly used in industry for unsaturated hydrocarbon gases (such as ethylene, propylene, butadiene, etc.) Drying, drying of polar liquids (such as ethanol, etc.), is a desiccant required for deep drying, refining, and polymerization of gas-liquid phases in petroleum and chemical industries.
