Low cost rapid route for hydrothermal synthesis of nano ZSM-5 with mixture of two, three and four structure directing agents

摘要

This article aims at investigating the effect of different structure directing agents such as TPAOH, TPABr, EDA and ethanol solely or as dual, triple or quad mixture on the synthesis and characteristics of nano ZSM-5 zeolite such as crystallinity and crystal size, and also its catalytic properties in MTG process. It is found out that application of a quad mixture of different structure directing agents not also reduces the synthesis cost compares to samples synthesized with one template but also ZSM-5 with small particle size, high crystallinity and improved catalytic properties will be obtained in a short crystallization period.
