Abstract: [Fe]ZSM-5 Zeolite was synthesized successfully in a alkaline medium by the hydrothermal crystallization method without amines as the templates.The structure of [Fe]ZSM-5 zeolite was identified by means of XRD,TEM,IR,EPR,XPS and Mossbauer spectroscopies.It was proved that the structure of product is a typical ZSM-5 type and Fe3+ ions were introduced into the ZSM-5 framework and were in the lattice of zeolite with a tetrahedral environment.In the conversion reaction from methanol to gasoline he catalytic activity and selectivity of H[Fe]ZSM-5 zeolite synthesized without amines are the same as those of H[Fe]ZSM-5 zeolite synthesized with amine and are much better than those of H[Al]ZSM-5 zeolite.The selectivity for C5+ products is over 80% and the components of aromatic hydrocarbons and isoalkanes in C5+ products are over 75%.
Key words: Synthesis of [Fe]ZSM-5 zeolite without amine, Study of Fe3+ coordination environment by spectroscopies, Improved MTG process
