A reformed gas stream is produced from a gaseous hydrocarbon feedstock stream containing both carbon dioxide and sulphur compounds, by subjecting the feedstock stream to a membrane separation process thereby producing a permeate stream containing at least part of the carbon dioxide and sulphur compounds, combusting the permeate stream and recovering energy from the combustion products, subjecting the impermeate stream to desulphurisation by passage over a bed of a particulate absorbent for hydrogen sulphide, thereby producing a desulphurised impermeate stream, adding steam to said impermeate stream, and subjecting the mixture of steam and said desulphurised impermeate stream to steam reforming over a steam reforming catalyst. The permeate stream may be used as fuel for the reforming, which latter may be a two-stage process. |
