A novel injector/reactor apparatus and an efficient process for the partial oxidation of light hydrocarbon gases, such as methane, to convert such gases to useful synthesis gas for subsequent hydrocarbon synthesis. Sources of a light hydrocarbon gas, such as methane, and oxygen or an oxygen-containing gas are preheated and pressurized and injected through an injector means at high velocity into admixture with each other in the desired proportions, preferably at comparable momentums, at a plurality of mixing nozzles which are open to the reaction zone of a reactor and are spaced over the face of the injector, to form a reactant gas premix having a pressure drop equal to at least 1% of the lowest upstream pressure of either of said gas streams. The gas premix is ejected in a time period which preferably is less than 9 milliseconds, at a velocity between about 25 to 1000 feet/second, into a reaction zone comprising a partial oxidation zone, so that the gas mixture reacts therein. The partially-oxidized effluent is then passed into a steam reforming catalyst zone to reduce the amounts of CO.sub.2, H.sub.2 O and heat produced by the partial oxidation reaction to form the useful syngas, which is cooled, recovered and/or further processed.

[ What is claimed is:] [1.] An autothermal process for the partial oxidation and steam reforming of hydrocarbons to form synthesis gas containing hydrogen and carbon monoxide, comprising providing individual streams of hydrocarbon gas and oxygen or an oxygen-containing gas, each stream being at independent elevated temperatures and pressure of 10-100 atmospheres, injecting said individual streams into admixture with each other through an injector means having a plurality of mixing nozzles and having separate passages for the hydrocarbon gas and the oxygen or oxygen containing gas, the pressure drop in the passages being at least 1% of the lowest upstream pressure of either of said gases, passing the resulting gaseous premix from the plurality of mixing nozzles into a partial oxidation reaction zone in less than 9 milliseconds after the pre-mix is formed to form a partially oxidized gaseous reaction mixture, passing the partially oxidized reaction mixture into a catalytic steam reforming zone to produce said synthesis gas, and recovering said synthesis gas.
