Abstract: Industrial production of methanol from methane is commonly achieved by a two-step process,which means high energy consumption and high cost.A one-step method for methane steam reforming to methanol is developed by coupling plasma with Cu-based catalyst using a coaxial dielectric barrier discharge reactor.The reaction conditions for CH4/H2O/Ar over plasma and the catalytic performance of Cu/SiO2 catalyst are investigated.Experimental results show that the optimum reaction temperature is 170℃,and the best CH4/H2O molar ratio is 1∶4.Under the optimized reaction conditions,the conversion of methane can achieve 6.4% and the selectivity of methanol can reach 58.8% when employing Cu/SiO2 catalyst with a loading of 5 wt%.
