| 摘 要： | The influence of adding Fe,Cr,Co,and Ga into 3%Mo/HZSM-5 catalyst on methane aromatization,and the influence of additives ratio on methane conversion,selectivity to hydrocarbons and coke,as well as distribution of aromatics were investigated.The experimental results showed that the addition of Fe,Cr,Co and Ga promoted the dehydrogenation and dissociation of methane.The results of NH3-TPD indicated that the acidity of HZSM-5 was changed by adding Fe and Co components,consequently the catalytic properties of Mo/HZSM-5 were changed.It was also revealed that strong acid sites were the center of methane aromatization.The results of XRD characterization showed that the crystallinity of Mo on ZSM-5 zeolite was increased after adding Fe,Co additives.

| Abstract: | The influence of adding Fe, Cr, Co, and Ga into 3%Mo/HZSM-5 catalyst on methane aromatization, and the influence of additives ratio on methane conversion, selectivity to hydrocarbons and coke,as well as distribution of aromatics were investigated. The experimental results showed that the addition of Fe, Cr, Co and Ga promoted the dehydrogenation and dissociation of methane. The results of NH3-TPD indicated that the acidity of HZSM-5 was changed by adding Fe and Co components, consequently the catalytic properties of Mo/HZSM-5 were changed. It was also revealed that strong acid sites were the center of methane aromatization. The results of XRD characterization showed that the crystallinity of Mo on ZSM-5 zeolite was increased after adding Fe, Co additives. |
