| Abstract: | Four Zn/ZSM-5 catalyst samples were prepared by mechanical pressing,introducing binder of aluminum oxide,introducing binder of silicon oxide,and binderless molding,respectively.The samples were characterized by N2 physical adsorption,scanning electron microscopy,NH3 temperature-programmed desorption,pyridine Fourier transform infrared spectroscopy,and X-ray photoelectron spectroscopy and were evaluated by aromatization of mixed C4 hydrocarbons.The results indicated that,compared with the mechanical pressed ... |
