Abstract

Provided is a process for producing a hydrogen-rich synthesis gas stream from an input gas stream containing hydrocarbons. The process providing the input gas at a pressure between 20 and 80 bara, adding a first process steam stream to obtain a first process gas mixture, prereforming the mixture in a shaft reactor to reduce the content of higher hydrocarbons, autothermal reforming with a second process steam and oxygen stream to produce a hot raw synthesis gas, cooling the hot raw synthesis gas in a waste heat boiler (116, 316), converting the cooled raw synthesis gas in high and low temperature Co conversion stages with catalysts, and separating CO<2> in a physical scrubbing apparatus using methanol as the scrubbing medium. The result is a hydrogen-rich synthesis gas stream and a CO<2>-rich gas stream. The process does not include any further reforming steps in a steam reformer with catayst-filled reformer tubes heated using burners.
