Product Introduction
High-silica ZSM-5 is a new type of zeolite developed upon ZSM-5 with SiO2/Al2O3 mole ratio from 120 to 700. Its structure is based on particular channel. It has high catalytic activity, hydrothermal and thermal stabilities. It could be used as carrier of catalyst in processes of petrochemical, such as dewaxing, forming gasoline from methanol, isomerization of xylene, toluene disproportionate interconversion of hydrocarbons, alkylation of aromatic compounds, aromatization of paraffins, and cracking by catalyst to enhance octane number of gasoline. It also can be used as active composition or carrier of catalyst in fine chemicals production.
