Claim:
1. A process for producing a synthesis gas mixture, the method comprising the steps of: (a) providing a hydrocarbon material which is gas and/or liquid; (b) subjecting the hydrocarbon material to catalytic partial oxidation (CPO) so as to produce a first synthesis gas mixture comprising carbon monoxide, hydrogen and carbon dioxide; (c) adding liquid water to the first synthesis gas mixture obtained in (b) in an amount such that said liquid water is completely vaporized and said liquid water, without further addition of steam, results in a second synthesis gas mixture comprising vaporized water in an amount appropriate to conduct a water-gas shift reaction, said vaporized water resulting from said adding being present at 30 to 60 percent by volume relative to the total components of the second synthesis gas mixture; and no further steam is added in this step (c); and wherein the liquid water is preheated to a temperature of 120 to 250° C., and directly injected at 10-40 barg pressure and the addition of the liquid water results in cooling of the second synthesis gas mixture in less than 50 msec to a temperature appropriate to conduct a water-gas shift reaction.
