Abstract: Embodiments include a method and apparatus for converting a hydrocarbon and oxygen feed stream to a product stream such as syngas, including multiple serially aligned reaction zones and multiple hydrocarbon feeds. The first reaction zone catalyzes the net partial oxidation of the feed hydrocarbon. The subsequent zones catalyze reactions such as the stream or dry reforming of hydrocarbons or the water gas shift reaction, depending on the stream composition in the vicinity of the zone, and the desired product stream composition.
