ABSTRACT:
The present invention provides a process for the preparation of carbon monoxide and/or hydrogen from a hydrocarbon feedstock. The hydrocarbon feedstock is subjected in a first stage to a catalytic partial oxidation process in which it is contacted, as a gaseous mixture comprising the hydrocarbon feedstock and an oxygen-containing gas, which gaseous mixture also comprises nitrogen, with a catalyst comprising as a catalytically active metal rhodium, iridium or platinum. At least a portion of the products of the first stage is subjected in a second stage to a process in which ammonia and/or hydrogen cyanide is removed.
