Description

Automatic production line for molecular sieve

Technical Field

Background

The molecular sieve is a kind of synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. The adsorbent is mainly used for organic chemical industry and petrochemical industry, is also an excellent adsorbent for coal gas dehydration, and purifies pollutants in air. The molecular sieve has the following types according to different pore diameters: 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 mordenite type, etc. The most basic structure of the framework of the molecular sieve is SiO4 and AlO4 tetrahedron, and the crystallization of the three-dimensional network structure is formed by combining common oxygen atoms. This combination forms voids and channels with molecular level and uniform pore size. The molecular sieve has high adsorption capacity, high selectivity and high temperature resistance.
