ZSM-5 Zeolite
Synthesis of ZSM-5 by direct method
ZSM-5 zeolite is synthesized directly by reacting soluble glass with aluminium sulphate to ZSM-5 zeolite, not using organic amine. This product has been used as the parent of alkylationm, isomeration, aromatization and dewaxing catalysts and so on. The ZSM-5 zeolite, characteristic of the simpler synthesis process, stabler quality, free of pollution, less cost, better hydrothermally.
