METHOD FOR PRODUCING CO SYNTHESIS GAS Russian patent published in 2018 - IPC C10J3/00 C01B3/02 C01B32/00 B01J23/00 

FIELD: technological processes.

SUBSTANCE: invention relates to a process for the production of synthetic gas from a greenhouse gas – carbon dioxide (CO₂) by catalytic conversion of it into synthetic gas and combustible gas. Process is carried out by means of hydrogenation conversion CO₂ by contacting a reaction mixture containing hydrogen (H₂) and CO₂ with a fixed-bed catalyst, which is a metal supported on the support, at an elevated temperature. In this case, as the metal, the catalyst contains iron in an amount of 0.5–15 mass%, and the process is carried out under supercritical conditions for CO₂ at a pressure above 73.8 atm and a temperature of 450 to 600 °C when feeding into the reactor a reaction mixture containing a mixture of H₂ and CO₂, taken in a molar ratio of 0.25–1:1, respectively, and a space velocity from 5,500 to 45,000 h^-1.

EFFECT: technical result is to increase the productivity of the process of processing and utilization of CO₂, and also in the increase in the life of the catalyst.
