Partial oxygenation reactor

An apparatus for partial oxidation comprising:

• a mixing chamber configured to receive a first gas feed stream and a second gas feed stream, wherein one of the first gas feed stream and the second gas feed stream includes a hydrocarbon-containing gas while the other includes an oxygen-containing gas, the mixing chamber includes:
• an outer tube section having a first input port configured to receive the first gas feed stream;
• an internal flow diverter mounted internally to the outer tube section, the internal flow diverter having a second input port that receives the second feed gas stream, the internal flow diverter having a flow diverter wall that defines a central flow channel configured for the second gas feed stream to flow therethrough, the flow diverter wall defining a plurality of gas dispersing channels configured to permit the second gas feed stream to flow out of the internal flow diverter and into a mixing zone defined by the outer tube section and the flow diverter wall, wherein the plurality of gas dispersing channels includes subsets of gas dispersing channels oriented with at least two different angles with respect to the flow diverter wall to promote mixing of the first gas feed stream and of second gas feed stream to form a reactive mixture;
• a tubular flow reactor in fluid communication with the mixing chamber and configured to receive the reactive mixture, the tubular flow reactor configured to support the partial oxidation of the hydrocarbon-containing gas as it flows axially therethrough;
• and
• a controller configured to regulate flow of the first gas feed stream and the second gas feed stream.
