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 recovery and/or 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 relative proportions, at a plurality of mixing nozzles which are open to the catalytic partial oxidation reaction zone and are uniformly-spaced over the face of the injector means, to form a reactant gaseous premix having a pressure drop equal to at least about 3% of the lowest upstream pressure of either of said gases. The gaseous premix is injected in a time period which is less than its autoignition time, preferably less than 9 milliseconds, at a velocity between about 25 to 1000 feet/second, into a catalytic partial oxidation zone so that the gaseous premix reacts in the presence of the fixed catalyst to reduce the amounts of CO.sub.2, H.sub.2 O and heat produced by the partial oxidation reaction, to form a useful syngas which is cooled and recovered.

[ What is claimed is:] [1.]1. A process for the catalytic partial oxidation of a hydrocarbon gas to synthesis gas containing hydrogen and carbon monoxide, comprising providing individual streams of a hydrocarbon gas and oxygen or an oxygen-containing gas, each stream being at independent elevated temperature and a pressure of 10 atmospheres or more, 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 3% of the lowest upstream pressure of either of the streams of the individual gases, and obtaining a uniform flow of each of said gases through the injector means, forming a gaseous premix, passing said gaseous premix from the plurality of mixing nozzles within a time period shorter than its autoignition time into a catalytic partial oxidation reaction zone, containing a catalyst retained in fixed arrangement, to form said synthesis gas, and cooling and recovering said synthesis gas.
