Molecular sieve and activated alumina What is the difference

activating molecular sieves and activated alumina belong to the same industrial sorbent adsorption mechanism are the same, in general do-liquid adsorption, molecular sieve and activated alumina in general with the use of activated alumina general points in the lower part of the purification do pretreatment, molecular sieves Late relatively fine purification for adsorption.Molecular sieve absorption ability, for the purification of gas, should be saved to avoid direct exposure to the air. Should be reproduced before the molecular sieve and has longer storage time of use of the absorbent. Zeolite avoid oil and liquid water. Should be used to avoid contact with the oil and liquid water. Activated alumina ball is mainly used in chemical, metallurgy, electronics, oil and other industrial gases such as dried air, oxygen, nitrogen and other permanent gases smelt gas and oil cracking gas. I produced the activated alumina is a multi-pore, high-intensity x-ρ-alumina product  have a strong affinity for water is a water depth of desiccant drying trace. Use medium has soaked in water the same soft, not inflated, not powder dry phase characteristics, textile industry, oxygen and industrial automation instrument air dry. 13X molecular sieve adsorption equilibrium static water can reach about 23%. Activated alumina 17% of the way.
