Abstract:
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.
