Abstract

A process for the production of a hydrogen containing gas stream comprises partially reforming a feed stream containing hydrocarbon feedstock to be reformed together with a steam and/or carbon dioxide as reforming gas by passage of said feed stream over a steam reforming catalyst disposed in heated auxiliary tubes, thereby forming a partially reformed gas stream; subjecting the partially reformed gas stream, optionally together with a further quantity of said feedstock and/or reforming gas, to further reforming by passage over a steam reforming catalyst disposed in furnace reformer tubes heated by combustion of a fuel, thereby forming a reformed product gas stream; and passing the reformed product gas stream past the exterior of the auxiliary tubes, thereby supplying heat to said auxiliary tubes and cooling the reformed product gas stream.
