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.

Process for the preparation of carbon monoxide and/or hydrogen

Process for upgrading a paraffinic feedstock which includes: a) supplying the feedstock and an olefins-containing stream at a paraffin to olefin volume ratio greater than 2 to a reactor containing a zeolite-beta catalyst; and b) removing the upgraded product; wherein the process is operated at an olefin conversion of at least 90 mol % in an external circulation reactor having an extent of external circulation of liquid reactor content expressed as ##EQU1## of greater than 2 wherein .phi./v is the volumetric flow rate of feedstock and olefins-containing stream and .phi./vc is the volumetric external circulation flow rate, and upgraded products produced by the process.

Process for upgrading a paraffinic feedstock

A catalyst comprising a silica-containing carrier on which a metal component iron, nickel, or cobalt promoted by zirconium is supported snd, in addition, as promoter a noble metal from Group VIII of the Periodic Table; the promoter cobalt/zirconium catalyst is suitable for the preparation of hydrocarbons from carbon monoxide and hydrogen.
