ABSTRACT:
Soot formation is suppressed in the preparation of hydrogen and/or carbon monoxide rich gas by arranging on at least a surface of an upper portion of a reactor a catalytic material which is active in steam reforming hydrocarbons, introducing a hydrocarbon feedstock and an oxygen-containing atmosphere into the upper portion of the reactor, partially oxidising the feedstock with oxygen in the upper portion of the reactor, and contacting a part of the partially oxidized feedstock with the reforming catalyst in the reactor upper portion.
