A mixture of hydrocarbons, oxygen and steam is reacted over a fluidized bed, in a first reaction stage, at high temperature to produce, at hydrocarbon conversion levels ranging from about 85 percent to about 92 percent, a reaction product of hydrogen and carbon monoxide in admixture with unreacted hydrocarbons, carbon dioxide and steam. The level of hydrocarbon conversion is further increased by about 0.5 to 5 percent by contacting and endothermically reacting the reaction product mixture over a fixed bed of a high void fraction catalyst in a second reaction stage.

In a process for the production of hydrogen and carbon monoxide, the steps comprising contacting, in a first reaction zone, low molecular weight hydrocarbons comprising methane, oxygen, and steam, at high temperature in a net reducing atmosphere, with a fluidized bed of catalyst, or catalyst and a solids diluent, to convert from about 85 percent to about 92 percent of the hydrocarbons to hydrogen and carbon monoxide and form a reaction mixture of hydrogen, carbon monoxide and unreacted hydrocarbons, oxygen and steam, withdrawing said reaction mixture as an effluent from said first reaction zone, and contacting said effluent, in a second reaction zone, with a fixed bed of catalytic metal solids with a void fraction of at least about 0.9 to convert, sufficient of the unreacted hydrocarbons, oxygen, and steam and increase the hydrocarbon conversion to a level ranging from about 0.5 percent to about 5 percent above that obtained in said first reaction zone.
