ZSM-5 series zeolite is a new type of molecular sieve synthesized with mechanical amine cations. Due to its many unique properties in chemical composition, crystal structure and physicochemical properties, it has shown good catalytic efficiency in many organic catalytic reactions, and has been more and more widely used in industry, becoming a promising new catalyst for petrochemical industry.
Molecular sieve crystalline silicate or aluminosilicate, silicon-oxygen tetrahedron or aluminum-oxygen tetrahedron are formed by the combination of oxygen bridges. ZSM-5 series zeolite is an aluminosilicate compound with a cubic lattice. Molecular sieves have a uniform microporous structure with uniform pore sizes. These pores can adsorb molecules smaller than their diameters in the interior of the pores, and have preferential adsorption capacity for polar molecules and unsaturated molecules, so molecules with different degrees of polarity, different degrees of saturation, different molecular sizes and different boiling points are separated, that is, " The role of "body" molecules, so it is called molecular sieve. Molecular sieves have the advantages of high adsorption capacity and thermal stability that other adsorbents do not have, so molecular sieves have been widely used.
