Rare-earth oxides (REO) also prevent the conversion of Al2O3 into α modification, reduce carbon deposition by accelerating the oxidation of carbon-containing compounds, which ensures a stable course of CO2-CM. The presence of REO in the above catalysts increases their sulfur resistance with a corresponding decrease in the degree of blocking the active catalyst surface by SO2. It is found that increasing the degree of dealumination of Ni-BEA zeolites increases their catalytic activity in the conversion of CH4-CO2 mixture and resistance to carbonization, while modification with ceria provides an additional increase in their activity. The principles of selection of catalytic systems for the CO2-CM process in the thermocatalysis conditions and plasma catalysis differ, which is due to the mechanism of these processes.
