NOVELTY - The process comprises reacting methanol with water at a temperature of 550 degrees C and a pressure of 3200 psig to produce hydrogen and carbon dioxide, where the weight ratio of the water to the methanol is 7-13. The process contains less than 2 g of fuel other than methanol and water per liter of methanol and water. The yield of the methanol converted to the hydrogen and carbon dioxide is 80 mole%.    USE - The process is useful for producing hydrogen, which is useful: in an internal combustion engine located on a passenger-type vehicle, a load-carrying vehicle, a moped, a scooter, a motorcycle, a three-wheeler, an automotive passenger vehicle, a pick-up truck, a semi-trailer truck, an industrial lift truck, a bus, a lawn mower, a rototiller, a backhoe, a tractor, a bulldozer, a power shovel vehicle, a construction vehicle, a train, a ship, a boat, a stationary internal combustion engine used in a factory, a manufacturing plant, a mining or crushing plant, a machine shop, an assembly plant, a foundry, a forging plant, a processing plant and a packing plant, where the internal combustion engine is a gasoline engine, a diesel engine, a biofuel engine, a liquefied petroleum gas engine or a compressed natural gas engine (all claimed) and is useful for industrial applications including home use, factories, manufacturing plants, mining and crushing plants, machine shops, assembly plants, foundries, forging plants, processing plants and packing plants; for production of ammonia, ethanol and aniline; for hydrocracking, hydroforming and hydrofining of petroleum; for hydrogenation of vegetable oils; for hydrogeno lysis of coal; for reducing agent for organic synthesis and metallic ores; for reducing atmosphere to prevent oxidation; as oxyhydrogen flame for high temperatures; for atomic-hydrogen welding; for instrument-carrying balloons; for producing hydrogen chloride and hydrogen bromide; for production of high-purity metals; as fuel for nuclear rocket engines for hypersonic transport; and for cryogenic research.    ADVANTAGE - The process allows efficient, reliable and catalyst free production of hydrogen thus improving the performance of the internal combustion engine.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an internal combustion engine.
