A process for the production of a hydrogen containing gas stream comprises catalytic steam reforming of a major hydrocarbon/steam stream in tubes heated by means of a fired furnace and catalytic steam reforming of a minor hydrocarbon/steam stream in auxiliary tubes heated by the reformed major strea

A process for the production of a hydrogen containing gas stream comprises catalytic steam reforming of a major hydrocarbon/steam stream in tubes heated by means of a fired furnace and catalytic steam reforming of a minor hydrocarbon/steam stream in auxiliary tubes heated by the reformed major stream, and mixing the reformed minor stream with the reformed major stream.

A process for the production of a hydrogen containing gas stream comprising: a) forming major and minor feed streams, each containing hydrocarbon to be reformed together with at least one gas selected from steam and carbon dioxide; b) forming a reformed major stream by passing the major feed stream

A process for the production of a hydrogen containing gas stream comprising: a) forming major and minor feed streams, each containing hydrocarbon to be reformed together with at least one gas selected from steam and carbon dioxide; b) forming a reformed major stream by passing the major feed stream over a steam reforming catalyst disposed in furnace reformer tubes heated by combustion of a fuel; c) passing the reformed major stream past the exterior of auxiliary reformer tubes, thereby supplying heat to said auxiliary reformer tubes and cooling the reformed major stream; d) forming a reformed minor stream by passing the minor feed stream over a steam reforming catalyst disposed in said auxiliary reformer tubes in a direction counter-current to the flow of the reformed major stream past the exterior of said auxiliary reformer tubes; and then e) mixing the reformed minor stream with the cooled reformed major stream.
