Abstract: An internal combustion engine is operated at fuel-rich conditions by adjusting one or more operating parameters such as, for example, a throttle, an ignition timing, a load coupled to the engine, a fuel pressure, power to a supercharger, and power to a preheater to maintain a specified engine speed and a temperature of an exhaust gas. Operating the engine under these conditions allows the engine to function as a reformer producing a synthesis gas comprising hydrogen and carbon monoxide.

Abstract: Synthesis gas containing nitrogen as the majority component is processed to increase the hydrogen to carbon dioxide ratio. Nitrogen, carbon dioxide, and other contaminants are subsequently removed by a purification unit to produce a purified hydrogen gas stream. A recycle stream within the purification unit helps achieve a hydrogen purity greater than 99.9 percent, and hydrogen recovery greater than 99 percent.
