Molecular Sieve

Molecular sieve is an aluminosilicate compound with cubic lattice. Molecular sieve has a uniform microporous structure, and its pores have uniform diameters. These pores can adsorb molecules smaller than its diameter into the inside of the cavities, and have preferential adsorption capacity for polar molecules and unsaturated molecules, so they can The degree of sex is different, the degree of saturation is different, the molecules of different molecular size and boiling point are separated, that is, they have the function of "sieving" molecules, so they are called molecular sieves. Because molecular sieves have high adsorption capacity, strong thermal stability and other advantages that other adsorbents do not have, molecular sieves have been widely used.
