A process and a plant for converting a carbon monoxide containing crude synthesis gas stream, generated in a multi-stage reformer and/or gasifier plant, by CO shift into a treated syngas stream depleted with regard to carbon monoxide, but enriched with regard to hydrogen and carbon dioxide. To this end, the crude synthesis gas stream is routed to a CO shift reaction section, comprising at least a first shift reactor and possibly also comprising further downstream shift reactors, wherein the first shift reactor comprises at least two subreactors(7a, 7b) which are operated in parallel, wherein the at least two subreactors(7a, 7b) contain different volumes of the shift catalyst. |
