Product Introduction
ZSM-5 is an aluminosilicate zeolite. The structure is based on channels with insecting tunnels. Its primary channel is 10-membered ring with the window size of 5.4Å × 5.6Å. 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 FCC promoter. It could be used as active composition or carrier of catalyst in fine chemicals production.
