Termodynamic Basis of Methane Oxidation Dimerization Reaction and Process Approval
The article studied the kinetic laws of the catalytic dimerization reaction of methane. To study the kinetic laws of the methane dimerization reaction, the effect of partial pressures of methane and oxygen on the rate of ethylene formation at a temperature of 700 ÷ 8000C and a volumetric velocity of 600 ÷ 1200 h-1 was examined. An increase in the CH4: O2 ratio leads to a decrease in methane and oxygen conversion. The introduction of ethane, ethylene, CO and CO2 into the reactor has been shown to reduce the formation of products. Based on the kinetic laws, the mechanism of activation of the methane molecule has been proposed. The article also evaluates the process from a thermodynamic point of view. Based on the results obtained, the process of catalytic dimerization of methane was optimized.
