Abstract:In this paper, the ZSM-5 zeolite was synthesized using coal-series kaolin as material, sodium silicate, fumed silica, silicon acetate and silicic acid as silicon sources, sodium hydroxide as mineralizer and tetrapropylammonium hydroxide as template. Then, HZSM-5 was synthesized by exchanging ion in ammonium chloride. The HZSM-5 samples were characterized by XRD, SEM,FTIR, NH3-TPD and BET. Finally, the catalytic performance of HZSM-5 samples were evaluated by Methanol to Gasoline(MTG) reaction. The results indicate that the HZSM-5 molecular sieve synthesized from silicic acid has an excellent catalytic performance, starting to deactivate at 43 h after MTG reaction, and the selectivity of higher hydrocarbons products was 38.99%.
