A catalyst has a long life span and efficiently separates hydrogen from water. A first metal element (Ni, Pd, Pt) for cutting the combination of hydrogen and oxygen and a second metal element (Cr, Mo, W, Fe) for helping the function of the first metal element are melted in alkaline metal hydroxide or alkaline earth metal hydroxide to make a mixture heated at a temperature above the melting point of the hydroxide to eject fine particles from the liquid surface, bringing steam into contact with the fine particles. Instead of this, a mixture of alkaline metal hydroxide and metal oxide is heated at a temperature above the melting point of the alkaline metal hydroxide to make metal compound in which at least two kinds of metal elements are melted, and fine particles are ejected from the surface of the metal compound to be brought into contact with steam.

The apparatus contains a means to create superheated steam at a temperature of preferably 800° C. The superheated steam is delivered to a catalytic decomposition converter that contains ceramic membranes that function to decompose water H2O into its constituent elements of diatomic hydrogen and oxygen. In one embodiment, a cascade of catalytic cells, one set for hydrogen and one set for oxygen are arranged in a unique “Cascade and Recirculate” configuration that greatly improves the throughput of the catalytic process. Only enough hydrogen is produced and delivered to the fuel cell according to the real time demand. There is no hydrogen storage on board. An electrically heated boiler initializes the process, and thereafter the heat from the exothermic reaction of a high-temperature fuel cell, and a small hydrocarbon burner sustains the operational superheated steam temperature. By using the by-product heat of a high temperature fuel cell in conjunction with the efficient combustion of a small amount of conventional hydrocarbon fuel, a unique thermodynamic hybrid system is created. The electrical energy generated by the fuel cell is used to maintain the charged state of a traction battery. A plurality of pumps, valves, regulators and sensors under microprocessor control manage the processes.

The present invention involves methods and apparatus for supplying fuel for a hydrocarbon and water hybrid engine. Water may be supplied from a water supply source to a steam chamber disposed with an exhaust conduit. Heat may be conducted from the exhaust conduit to the steam chamber to produce steam. The steam may be flowed to a catalytic converter that may have a substrate element disposed therein with the substrate element coated with an oxide that may be oxidizable with steam and reducible back to the original state without use of a chemical agent while producing oxygen. The steam may be converted to hydrogen and oxygen and the hydrogen and oxygen may be flowed to an intake port of the internal combustion engine. The steam and catalytic converted hydrogen and oxygen may be used as an energy source and the hydrogen and oxygen may be converted to heated water for recycling as a steam source.

This invention presents improved combustion methods, systems, engines and apparatus utilizing H2, O2 and H2O as fuel, thereby providing environmentally friendly combustion products, as well as improved fuel and energy management methods, systems, engines and apparatus. The Water Combustion Technology; WCT, is based upon water (H2O) chemistry, more specifically H2O combustion chemistry and thermodynamics. WCT does not use any hydrocarbon fuel source, rather the WCT uses H2 preferably with O2 and secondarily with air. The WCT significantly improves the thermodynamics of combustion, thereby significantly improving the efficacy of combustion, utilizing the first and second laws of thermodynamics. The WCT preferably controls combustion temperature with H2O and secondarily with air in the combustion chamber. The WCT preferably recycles exhaust gases as fuel converted from water. The WCT minimizes external cooling loops and minimizes exhaust and/or exhaust energy, thereby maximizing available work and internal energy while minimizing enthalpy and entropy losses.
摘要:
The system is based on a recirculating Carbon Flow Loop, within which toxins in municipal waste or other feedstock are neutralized in a plasma reactor, by using an electric arc in ionized gas to generate ultra high temperatures. This breaks down substances into their basic molecules, and transforms the feedstock into syngas (which is comprised predominantly of hydrogen and carbon monoxide). This can be processed by a water shift reactor, an engine driven electric generator or another exothermic device where carbon monoxide is transformed into carbon dioxide. This continues flowing in the carbon loop to an Algae Bioreactor. Here photosynthesis of the algae transforms the carbon dioxide to become part of an oil rich carbohydrate. This can either continue to the next stage as feedstock and recirculate again around the Carbon Loop and/or exit, and be used to manufacture biofuel or other substances.

The invention provides processes and apparatus for producing hydrogen from water, including the steps of heating water to a water dissociating temperature to form a dissociated water reaction mixture comprising hydrogen gas and oxygen gas. A vortex is formed of the reaction mixture to subject the reaction mixture to a centrifugal force about a longitudinal axis of an interior space of a vortex tube reactor, so that there is radial stratification of the hydrogen gas and the oxygen gas in the interior space of the vortex tube reactor. Hydrogen or oxygen is preferentially extracted from the reaction mixture at spaced apart points along the length of the interior space of the vortex tube reactor.
