TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Process: The hydrogen generator is an electrolysis apparatus, fuel cell, fuel processor, a reformer, a cold fusion apparatus, or other apparatus for producing hydrogen. The fuel cell is a proton exchange fuel cell, a solid oxide fuel cell, alkaline fuel cell, a direct methanol fuel cell, molten carbonate fuel cell, phosphoric acid fuel cell or a regenerative fuel cell. The reformer reforms a hydrocarbon fuel to the hydrogen gas with the aid of steam. In the reformer steam is used to heat a fuel as it passes over a catalyst provided in the generator. The fuel and steam are cracked in the hydrogen generator to form hydrogen gas. The hydrogen generator produces hydrogen in combination with oxygen, nitrogen, water, ethanol, carbon dioxide, carbon monoxide, hydrocarbons, methanol and/or methane. The methanol, methane or similar materials are produced in combination with hydrogen gas are produced from a fuel material such as diesel, petrol, or canola oil.Operation of the hydrogen generator is adjusted to produce a desired ratio of hydrogen to other components in (M1), by altering parameters such as the composition of materials introduced to the generator, velocities of gases to the various components, temperature and pressure of operation, the catalyst used, the amount of exposure to the reactor to the catalyst, and the type of generator used. The reformer is operated at 100-1000 (preferably at 200-900, more preferably 20-800) degrees C, and at pressure of 1-5 (preferably 1-3, more preferably at 2) bar. (M1) Is added to the engine directly or indirectly, or via further component such as a mixing chamber. The compression engine is a diesel engine. The system includes at least one heat exchanger. (M1) Is added to the engine or mixer separately or in combination with other components of the fuel (preferably separately).    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Catalyst: The catalyst used in the generator is selected from nickel, platinum, materials containing nickel and/or platinum.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The hydrocarbon produced in the generator is paraffin or hydrocarbon containing saturated bonds; or 1-20C hydrocarbon, preferably 2-12C, more preferably 8C hydrocarbon. (M1) Contains (in vol.%): hydrogen 0-50 (preferably 30-40, especially 35-48); carbon monoxide 0-25 (preferably 3-5, more preferably 4-5); hydrocarbons 0-5 (preferably 1-4, more preferably 2-3), carbon dioxide 0-25 (preferably 5-15, more preferably 3-10); and the balance of nitrogen.
