METHOD FOR UTILIZATION OF CONVERTER GASES FOR THE PRODUCTION OF LIQUID FUEL FROM HYDROGEN-CONTAINING SYNTHESIS GAS Russian patent published in 2023 - IPC C21C5/38 C10J1/26 C10L1/02 

FIELD: ferrous metallurgy.

SUBSTANCE: invention relates to oxygen-converter production, and is aimed at reducing direct emissions of CO₂ into the atmosphere when it is used in the process of obtaining liquid synthetic fuel. In the well-known method for the utilization of converter gases for the production of liquid fuels, based on the removal of converter gas, which is formed in the process of blowing the converter, its mixing with natural gas to obtain ECA synthesis gas, which is cooled and water vapour is obtained, then ECA synthesis gas is mixed with steam followed by a water shift reaction, as a result of the water shift reaction synthesis gas with an increased proportion of hydrogen is obtained, which is then cooled, the process condensate is separated and sent for compression, and then carbon monoxide reductive oligomerisation reactions are carried out to obtain a mixture of liquid synthetic fuel and the gas phase, which is sent for cooling and subsequent separation of the gas and liquid phases, after which the liquid phase is separated into water and liquid synthetic fuel.

EFFECT: synthesis gas with an increased proportion of hydrogen is obtained.
