This invention concerns a process for the catalytic partial oxidation of a hydrocarbon feedstock. The process comprises contacting a feed mixture comprising the hydrocarbon feedstock and an oxygen-containing gas, which feed mixture also comprises nitrogen, with a catalyst capable of catalyzing the partial oxidation of the hydrocarbon feedstock, wherein the feed mixture also comprises a sulfur-containing compound. This process allows sulfur-containing hydrocarbon feedstocks to be processed without first undergoing a sulfur removal treatment. Accordingly, a process for the preparation of carbon monoxide and/or hydrogen from a hydrocarbon feedstock comprises subjecting the hydrocarbon feedstock in a first stage to a catalytic partial oxidation process as described above and subjecting at least a portion of the product of the first stage in a second stage to a desulfurization process.

Process for the catalytic partial oxidation of hydrocarbons

The present invention relates to a process for the catalytic partial oxidation of a hydrocarbon feedstock comprising contacting a feed comprising a hydrocarbon feedstock and an oxygen-containing gas with a catalyst at an elevated temperature under conditions such the catalyst will be susceptible to a thermal shock, the catalyst having the form of a porous monolithic structure and comprising a catalytically active metal supported on a zirconia-based carrier.

A process for the catalytic partial oxidation of a hydrocarbon feedstock comprises contacting a feed comprising a hydrocarbon feedstock and an oxygen-containing gas with a catalyst in a reaction zone, which catalyst is retained in the reaction zone in a fixed arrangement having a tortuosity of at least 1.1 and having at least 750 pores per square centimeter.

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.
