What is a Molecular sieve? A molecular sieve has a uniform micropore structure, its hole diameter size uniform, the holes can be smaller than its diameter molecular adsorption into the inner cavity, and the polar molecules and unsaturated molecules have priority adsorption capacity, and can put the polarity degree, saturation, different size and boiling point of different molecules, which has the effect of "sieve" molecules, so-called molecular sieve because the molecular sieve has high adsorption capacity, strong thermal stability, and other adsorbents so that the molecular sieve is widely used.
Main uses of Molecular sieve A molecular sieve is mainly caused by molecular gravity to produce a "surface force" on the fixed surface. When the fluid flows, some molecules in the fluid will do irregular movement and collision on the surface of the adsorbent. On the fixed surface, the number of molecules reduces the effect of separation; the holes, with strong polarity on the zeolite sieve surface, induce strong adsorption. Because molecular sieve has a strong adsorption capacity for water and carbon dioxide, in molecular sieve desulfurization, it has a strong adsorption capacity for water and other small molecular molecules; the pore size distribution of molecular sieve is very uniform and neat when the molecular diameter is less than the hole diameter, it will enter the hole of the molecular sieve. Thus, the various types of the molecular sieve are separated. Characteristics of the molecular sieve: Molecular sieve moisture absorption ability (therefore is widely used as a desiccant), for gas purification treatment, preservation should avoid direct exposure to air. The molecular sieve stored for a long time and already hygroscopic should be regenerated before use. Molecular sieves avoid oil and liquid water. Avoid contact with oil and liquid water when using. In industrial production, drying is air, hydrogen, oxygen, nitrogen, argon, etc. Two adsorption dryers are connected in parallel, one working, and the other one can be regenerated. Work and regenerate alternately to ensure the continuous operation of the equipment. The dryer operates at 8-12℃ and is regenerated at heating to 350℃. The regeneration temperature of the molecular sieve is slightly different. A molecular sieve has a good catalytic effect on some organic gas phase reactions. Price of Molecular sieve The different price of Molecular sieve purity is also different. The market price of Molecular sieves is in the process of dynamic change.
