Direct conversion of methane to higher hydrocarbons is an effective process to solve the problem of natural gas utilization. Although remarkable progress has been achieved on the dehydro-aromatization of methane (DAM), low conversion caused by severe thermodynamic limitations, coke formation, and catalysis deactivation remain important drawbacks to the direct conversion process. Molybdenum catalysts supported on HZSM-5 type zeolite support are among the most promising catalysts. This review focuses on the aspects of direct methane conversion, in terms of catalysts containing metal and support, reaction conditions, and conversion in different types of reactors. The reaction mechanism for this catalytic process is also discussed.
Mo/HZSM-5 catalyst exhibits the highest activity for non-oxidative methane conversion. Catalytic performance is influenced by silica/alumina ratio of the HZSM-5. Catalyst stability and selectivity to aromatics were improved, upon transition metal addition.Figure optionsDownload as PowerPoint slide
