| Abstract: | The Na Mn W/SiO 2 catalyst has been studied for oxidative coupling of methane (OCM) in a micro stainless steel reactor at elevated pressure and the effect of operating conditions, such as GHSV, pressure, temperature and CH 4/O 2 ratio, on the OCM has been also observed 15 7% conversion of CH 4 with 82 3% C 2+ selectivity was obtained at 750℃,GHSV 1 5×10 5h 1 , 0 6MPa with small output of C 3 and C 4 hydrocarbons It was found that the OCM reaction is strongly dependent on the operating conditions at elevated pressure, particularly dependent on GHSV and ratio of CH 4/O 2 Higher GHSV and CH 4/O 2 ratio are in favor of the reaction running |
