ZMS-5 molecular sieve is used as the parent of alkylation, isomerization, aromatization, dewaxing and degrading, FCC, and increasing the production of propylene and other catalysts. Compared with the synthesis of ZSM-5 from foreign organic amines, the product is simple in process, stable in quality, without pollution, low in cost and high in hydrothermal stability.
