OXIDATIVE DIMERIZATION OF METHANE: KINETICS OF THE REACTION

Аннотация

In this article, the textural properties of catalysts and the process of catalytic dimerization of methane using catalysts based on salts of alkali and alkaline-earth metals containing molybdenum and manganese oxides were studied. It was found that the catalytic conversion of methane takes place on the surface of a catalyst that adsorbs oxygen to form an active complex [ZOCH3]. It has been shown that the catalytic conversion of methane can be carried out simultaneously with the formation of ethane and ethylene. At the same time, the percentage of ethylene in the free volume of the reactor increases compared to ethane, which helps the reaction of ethylene formation without oxygen and catalyst. Phenomenological equations for the kinetics of the catalytic reaction of methane dimerization are formulated and rate constants and Arrhenius parameters are calculated.
