Abstract

A kinetic experiment in the process of dry reforming of methane was performed for the first time in a reactor with a membrane catalyst for the extractor mode, in which the hypothesis of activated mass transfer based on the phenomenon of thermal slip was used for the analysis of the results. The results obtained show that in both parts of the reaction space (in the retentate and in the permeate) of the membrane reactor, intensification of the intermediate stages of dry reforming of methane is observed, compared with the contactor modes. Unlike the contactor modes, in which the methane cracking stage is shifted toward the formation of products of this reaction, in the extractor mode, the process occurs near equilibrium, and the constants of the direct and reverse reactions are close. In this mode, the reverse reaction of the water shift is strongly shifted toward the formation of water gas.
