Study of methane carbonate conversion process in fixed catalyst layer in different membrane reactors

Abstract

The work studied the characteristics of membrane catalysts in the reaction of methane carbonate conversion as a model reaction. This process produces synthesis gas (a 1:1 mixture of Н2 and СО), which can be used to make many products, including synthetic fuels (in the FischerTropsch process). One of the serious problems of methane carbonate conversion is the presence of side reactions that prevent the production of synthesis gas with the required ratio of products (H2:CO=1:1).Membrane catalysts were investigated in carbonate conversion of methane and membrane catalytic reactors: extractor, contactor, and distributor. Carbonate conversion of methane was compared with their material performance characteristics in the ground state in a conventional catalytic reactor with a fixed catalyst bed on membrane catalysts in the contactor and distributor. As the main parameters of the process of catalytic methane carbonate conversion, the change of the main parameters of the process -the concentration of the components in the products, the degree of change of the initial reagents and the ratio of the resulting synthesis gas components, depending on the contact time - were considered. The work aims to study methane's carbonate conversion process in a fixed catalyst layer in different membrane reactors.
