Product details

Cationic Y molecular sieve. Its skeleton structure is the same as Y-type molecular sieve, white cubic octahedral crystal, cell composition is.

A synthetic silico-aluminate hydrate (bubble zeolite) or natural zeolite having the function of screening molecules. Its general chemical formula is (M '2M)O·Al2O3·xSiO2·yH2O, M', M are univalent and bivalent cations such as K+, Na+ and Ca2+, Ba2+, etc. It has a lot of uniform pore size and arranged holes in the structure, different pore size of molecular sieve separated molecules of different sizes and shapes. According to the different molecular ratio of SiO2 and Al2O3, different pore sizes of molecular sieves were obtained. Its models are: 3A(potassium A type), 4A(sodium A type), 5A(calcium A type), 10Z(calcium Z type), 13Z(sodium Z type), Y(sodium Y type), sodium mercerite type, etc. It has high adsorption capacity, strong selectivity and high temperature resistance. Widely used in organic chemical industry and petrochemical industry, it is also an excellent adsorbent for gas dehydration. More and more attention has been paid to the purification of waste gas.
