چکیده:

The 5wt% Na2WO4–۲wt% Mn/SiO2 catalysts have been prepared by the incipient wetness impregnation method and XRD, BET and TPR tests were performed on this catalyst. Then, its catalytic performance for the oxidative coupling of methane (OCM) was evaluated in a continuous quartz micro-reactor. Operational tests were performed on 800-900 o C temperature range, CH4/O2=3.4-4.6 ratio at atmospheric pressure and 30000 GHSV. All products selectivity, CH4 conversion and experimental reaction rates have been obtained in methane-oxygen co-feed with nitrogen as dilutant.
