ZSM-5 zeolite belonging to the MFI structure, with three channels, including a ten yuan ring straight channel and

A set of mutually perpendicular thereto sine ten yuan ring channels, aperture oval.

ZSM-5 zeolite has been widely used in petrochemical, coal chemical and fine chemical industry, such as catalytic cracking, diesel pour, catalytic dewaxing, shape-selective catalysis, straight-run gasoline to improve the octane aromatization, toluene disproportionation technology, xylene isomerization, conversion of methanol to gasoline, methanol, dimethyl ether and carbon dehydration hydrocarbon aromatization, C3-C4 fraction overlapping aspects of the system such as gasoline.
