ZSM-5 molecular sieve has excellent shape selective catalytic performance due to its unique pore structure and acid properties. It is widely used in petrochemical, coal chemical and fine chemical fields. ZSM-5 molecular sieve has been widely used in catalytic cracking, diesel oil pour point reduction,catalytic dewaxing, shape selective catalysis, aromatization, toluene disproportionation, xylene isomerization, methanol to olefins, methanol to gas oline, methanol to dimethyl ether, C3 C4 fraction superposition to gasoline and other processes.

SAPO-34 molecular sieve has extremely high specific surface area, good hydrothermal stability, rich proton acidity and ion exchange sites, and its unique eight membered ring three-dimensional poresystem makes it have excellent shape selective catalytic performance of small molecules. It is a widely used solid acid catalyst and cata lyst carrier. SAPO-34 molecular sieve has a very good application effect intheselective catalytic reduction of NOx and the catalytic process of methanol to light olefins.

TS-1 is a kind of molecular sieve material whose skeleton is composed of silica tetrahedron and titanium oxide tetrahedron. The introduction of tetra coordinated Ti in the skeleton gives it good catalytic performa nce. Combined with the use of H2O2 oxidant, it provides an excellent alternative for many traditional oxidation reactionprocesses with high toxicity and high pollution. In recent years, as anew generation of green catalytic oxidation technology,TS-1 has become a hot spot of attention of many researchers.
