An experimental study of the potential autothermal reactor operation for the ethylene production via oxidative coupling of methane based on the ignition-extinction behavior for a Mn-Na2WO4/SiO2 catalyst is presented. The possibility of benefiting from the heat released during the reaction is analyzed. The effect of different process variables, challenges, and limitations on the autothermal oxidative coupling of methane reactor operation are investigated in which a moderately large amount of heat appears.
