Molecular sieve is a desiccant necessary for deep drying,refining and polymerization of gas-liquid phase in petroleum and chemical industry.
Adsorption and catalysis,molecular sieve as an ion exchanger,mainly used in environmental protection,soil improvement,water desalination and radiochemistry.it has a strong affinity for water and is therefore used in the laboratory for deep dehydration with extremely high drying potency.
