In this study, we synthesized ZSM-5 and doped ZSM-5 applying cations such as Zn(II) and Fe(II). Furthermore, we synthesized [Zn,Fe]-ZSM-5 using similar method for the first time. The final products were characterised by X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. On the other hand, the hierarchical mesoporous Zn-ZSM-5 zeolite catalyst was prepared by alkali treatment by NaOH and Zn impregnation, and its application in the conversion of methanol to gasoline (MTG) process was studied. The modified zeolite samples after modification were also characterized by FT-IR and XRD methods. Zn impregnated mesoporous catalyst Zn-Alk-Z5 exhibited dramatic improvements in...
