Abstract
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 relating proportions, at a plurality of mixing nozzles which are open to the partial oxidation zone of a reactor and are uniformly-spaced over the face of the injector means, to form a gaseous premix having a pressure drop through the injector. The gaseous premix is injected in a time period which is less than 5 milliseconds, preferably at a velocity between about 25 to 1000 feet/second, into a partial oxidation reaction zone so that the gaseous premix reacts therein, to reduce the amounts of CO.sub.2, H.sub.2 O and heat produced by the partial oxidation reaction and form, cool and recover a useful syngas.
