Zusammenfassung:The present invention relates to a process for desulfurizing a carbon-containing fuel stream (1), wherein the carbon-containing fuel stream (1) is supplied to a pre-reformer (2) for pre-reforming the fuel stream (1), wherein hydrocarbons of the fuel stream (1) having at least two carbon atoms are cracked into methane, hydrogen and carbon oxides by steam reforming in the pre-reformer (2) to obtain a desulfurized methane-containing stream (3) and wherein the pre-reformer (2) comprises a catalyst arrangement (4) for catalyzing the steam reforming. The process is characterized in that the catalyst arrangement (4) comprises a pre-catalyst (5) for catalyzing the steam reforming in a pre-catalyst receiver (6) and a main catalyst (7) for catalyzing the steam reforming in a main catalyst receiver (8), in that the pre-catalyst receiver (6) is spaced apart from the main catalyst receiver (8) and in that the fuel stream (1) passes through the pre-catalyst receiver (6) before the main catalyst receiver (8). The invention likewise relates to a corresponding plant for desulfurizing a carbon-containing fuel stream (1).
