In this study ZSM-5 catalyst was successfully synthesized without using template. In fact the purpose of synthesizing without use of template was recducing cost of synthesis and removal pollutions of template existence in structure. ZSM-5 catalyst has been synthesized by hydrothermal method at 195?C and 24 h.Then the properties of sample such as crystallinity, surface area, pore volume, crystal size ,… were characterized by XRD, FT-IR and BET surface area measurements. The results have been compared with a commercial type of ZSM-5.
