Molecular sieve storage method

Molecular sieve (also known as zeolite) is a microporous aluminosilicate crystal, which is mainly used in gas purification, petrochemical, refrigeration, automobile, architectural glass, medicine, coating, packaging and other fields. What should be paid attention to when storing it?

1. Molecular sieve has strong hygroscopicity. When stored, it should not be directly exposed to the air, but should be placed in a dry place. Molecular sieves that have been stored for a long time and absorb moisture should be regenerated before use.

2. Molecular sieves should avoid oil and liquid water. Oil will block the pores of molecular sieves, especially during the regeneration process, which may carbonize the oil and cause the pores to be blocked. Oil-gas and oil-water separation should be carried out before the molecular sieve tower. Since molecular sieves release heat when absorbing water, liquid water will release a lot of heat when it directly contacts the molecular sieve, which may cause danger or damage the performance of the molecular sieve.
