Kinetics of the Reaction of Oxidative Dimerization of Methane

Abstract

The article studies the process of catalytic dimerization of methane using catalysts based on salts of alkaline and alkaline- earth metals containing molybdenum and manganese oxides in their composition. The textural characteristics and morphology of the catalyst composition (Mo2O3)x·(Na2MoO4)y·(ZrO2)z, as well as the effect of carbon dioxide, argon and contact time on the reaction of catalytic dimerization of methane and the yield of the target product, were studied.
Optimization of the catalytic process of dimerization of methane was carried out, which showed that the process should proceed at a temperature of 750-800ºC at a controlled feed rate of the reaction mixture of gases in the catalytic zone of 0.3 mol/sec CH4 and 0.12 mol/sec O2. Phenomenological equations for the kinetics of the catalytic reaction of methane dimerization are compiled and the rate constants and Arrhenius parameters are calculated.
