Dependence of the product yield in the conversion of methane to carbonate on the type of reactor intended for receiving synthesis gas by converting methane.

In the article, the degree of conversion of methane and carbon dioxide, as well as the dependence of the selectivity for hydrogen on the flow rate of the initial mixture for the process of converting methane to carbon dioxide in a membrane (shell, curtain) reactor designed for the conversion of methane to synthesis gas of the "distributor" type at different temperatures is studied. At the same time, the conversion of methane and carbon dioxide was compared in "contactor" and "distributor" type (T=910°C) membrane (shell, curtain) reactors designed for synthesis gas by conversion of methane. The conversion of methane and carbon dioxide, as well as the observed hydrogen selectivity during the conversion process, in different types of membrane (shell, curtain) reactors designed for the conversion of methane to synthesis gas ("contactor" and "distributor") and in the usual reactor for the conversion of methane to synthesis gas compared. Contactor and distributor membrane (shell, curtain) hydrogen selectivity for reactors designed to obtain synthesis gas by conversion of methane was compared. When comparing the ratio of the reaction products of the mole ratio of hydrogen to carbon dioxide to the conversion of methane to carbon dioxide, then in the case of the "contactor" it does not exceed 0.6 (due to the occurrence of a side reaction), and for the "distributor" it exceeds one for all volumetric flow rates of the initial reactants.
