Synthesis gases are prepared by partial autothermal oxidation of liquid fuels and/or solid fuels in the presence of oxygen or oxygen-containing gases with the addition of a temperature moderator, such as steam and/or CO2, in an empty reactor space without baffles, at from 1000°to 1500°C. under from 1 to 100 bar, the reactants fuel and oxygen-containing gas being fed separately to the reactor, by a process in which the steam or CO2 is fed in simultaneously with the feed of the fuel, and the steam is let down through one or more nozzles into the fuel steam directly before the orifice for the fuel, let-down being effected at from 30 to 250%, preferably from 80 to 140%, of the critical pressure ratio. An apparatus for carrying out the process is also described.

In a process for the preparation of a synthesis gas by partial autothermal oxidation of a liquid or solid fuel in the presence of oxygen or an oxygen-containing gas with the addition of a gaseous temperature moderator selected from the group consisting of steam and CO2 and mixtures thereof, in an empty reactor space without baffles, at from 1000°to 1500°C. under from 1 to 100 bar, the improvement which comprises: feeding said fuel and oxygen-containing gas separately via feed pipes through concentrically arranged orifices opening into the reactor while feeding in the moderator gas simultaneously with the feed of the fuel and letting down the pressure of said moderator gas through one or more nozzles into the fuel stream at a point flush with or directly before the orifice for the fuel, said let-down being effected at from 30 to 250%, of the critical pressure ratio of said moderator gas.
