METHOD OF PRODUCING SYNTHESIS GAS FROM CO Russian patent published in 2017 - IPC C01B3/00 C01B31/00 B01J23/00 

FIELD: chemistry.

SUBSTANCE: method of producing synthesis gas during the hydrogenating conversion of CO₂ involves contacting the starting gas feedstock containing the mixture of H₂ and CO₂, with a catalyst at the temperature of 500-700°C, the atmospheric pressure and when supplying gas to the reactor at the molar ratio of H₂:CO₂=3.5-4:1 and the gas feed rate of 5000-10000^h-1, while the metal-containing catalyst is heated to the temperature of 500-700°C with the help of microwave radiation of low power up to 45 W. Herewith the catalyst is a metal deposited on the carrier, wherein the catalyst comprises molybdenum or indium as metal, and as a carrier, the catalyst comprises an actively absorbing microwave radiation material or a non-microwave absorbing material mixed with a catalytically inert material heating due to the absorption of microwave radiation.

EFFECT: providing the increased conversion, selectivity of formation, high productivity and complete absence of methane in reaction products, simplification of the process technology and reduction of energy costs.
