摘要

A process for the production of a hydrogen containing gas stream comprises catalytic steam reforming of a major hydrocarbon/steam stream (17) in tubes (2) heated by means of a fired furnace (5) and catalytic steam reforming of a minor hydrocarbon/steam stream (18) in auxiliary tubes (8) heated by the reformed major stream (12), and mixing the reformed minor stream with the reformed major stream (13, 14, 15).
