The Difference between Molecular Sieve and Activated Alumina

Molecular sieves have strong hygroscopicity and should be used for purification of gases. When preserved, direct exposure to air should be avoided. Molecular sieves with long storage time and moisture absorption should be regenerated before use. Molecular sieves avoid oil and liquid water. Avoid contact with oil and liquid water when using.

Activated alumina balls are mainly used for dehydration and drying of industrial gases, such as air, oxygen, nitrogen, smelting gas and petroleum cracking gas. Activated alumina produced by our company is an X-P type alumina product with many fine holes and high strength. It has strong affinity for water and is a desiccant for deep drying of trace water. It has the characteristics of water immersion in use medium, no softening, no expansion, no pulverization, liquid phase drying, textile industry, oxygen industry and automatic instrument air drying.
