ZSM-5II Zeolite is mainly used as the parent of such catalysts: alkylation, isomerization, amortization and dewaxing catalysts. In the same time, it is the indispensable additive of productive propylene addition agent.

ZSM-5II zeolite based on ZSM-5, used soluble glass and aluminium sulphate to synthesize directl, through optimizing reaction condition, not adding template. It has large specific surface area and high total acid. It has higher product yield coefficient and longer useful time under the same active of catalyst. The character of finer particle size and more even is benefit to the preparation of catalyst, enhanced the intensity of catalyst, and reduced the fray of catalyst. The average particle size is less than 2.5 micron.
