Current synthetic Zeolite molecular sieve It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and can be regenerated at high temperature. It is widely used in the fields of adsorption, separation, catalysis and environment, and is more suitable for the treatment of high air volume and high concentration organic waste gas. Natural zeolite, with different pore sizes, can prevent explosion boiling with bubbles, but can not meet the high efficiency requirements of industrial production. Zeolites present a certain degree of chemical equilibrium when they are generated, so they can be regarded as a mineral called zeolite phase. This zeolite phase is metastable, that is, it can be artificially synthesized and exist together stably to a certain extent. Zeolite molecular sieves have more advanced functions, such as screening molecules, acting as catalysts, slow release catalysts, etc., so they have certain requirements for pore size, uniform distribution, and are often artificially synthesized. The following are the differences between the two

1. The chemical composition of natural zeolite molecular sieve is different. The chemical composition of natural zeolite molecular sieve is sodium aluminosilicate, while molecular sieve is crystalline silicate

2. Different characteristics

Zeolite has glassy luster, which can be reabsorbed or other liquids. Molecular sieve has the advantages of high adsorption capacity, strong thermal stability and other advantages that other adsorbents do not have

3. Different characteristics

Molecular sieve is powder crystal with metallic luster, hardness of 3-5, relative density of 2-2.8. Natural zeolite is colored, synthetic zeolite is white, insoluble in water
