Molecular sieve is a type of adsorbent or thin film material with uniform micropores, mainly composed of silicon, aluminum, oxygen, and other metal cations. It has a crystal structure and characteristics, with a solid skeleton on the surface and internal pores that can adsorb molecules. Its characteristics are large adsorption capacity, high efficiency, strong selectivity, high hydrophobicity, and strong thermal stability. The application of zeolite molecular sieve has been widely used in the fields of petrochemicals, environmental protection, biotechnology, food industry, pharmaceutical and chemical industry.
