The JOOZEO 3A molecular sieve is made of sodium-potassium aluminosilicate, with crystal pores about 3Å (0.3 nm) wide. This small pore size allows it to specifically trap small molecules like water, and it can be reused after high-temperature purging or vacuum desorption. It’s commonly used to dry unsaturated hydrocarbons (such as ethylene, propylene, butadiene), natural gas, carbon dioxide, kerosene, jet fuel, polar liquids like ethanol, and refrigerants. In the petrochemical and chemical industries, it is often applied as a desiccant for deep drying, refining, and polymerization.
