ZSM*5 Series Shape-selective Zeolites
ZSM*5 zeolite could be used for petrochemical industry, fine chemical industry and other fields because of its special three-dimensional cross straight pore canal, special shape-selective crackability, isomerization and aromatization ability. Presently, they can be applied to the FCC catalyst or additives that can improve the gasoline octane number, hydro/nonhydrodewaxing catalysts and the unit process xylene isomerization, toluene disproportionation and alkylation. The gasoline octane number can be enhanced and the olefin content can be also increased if the zeolites are added to the FCC catalyst in the FBR-FCC reaction. In our company, the ZSM*5 serial shape-selective zeolites have different silica-alumina ratio, from *5 to **0. The particle distribution can be adjusted according to the clients' requirements. The isomerization ability and activity stability can be changed when the acidity is adjusted by changing the silica-alumina ratio according to your requirements.
Synthesis Process
Under high temperature and high pressure conditions, the ZSM*5 zeolites will be produced after hydrothermal compound crystallization, filtrating, washing, modifying and drying by using aluminum salt and silicate as main material.
