Processes and systems for generating hydrogen gas from resonant cavities are disclosed. A preferred version includes separating a resonant cavity into two compartments with a dielectric type diaphragm, injecting gases such as ammonia into one compartment and generating electromagnetic energy from an antenna, microwave generator or waveguide into the other compartment so that a plasma discharge is formed in the cavity, and hydrogen gas can be selectively released from an outport of the cavity.

摘要:
Ammonia is used as precursor source of hydrogen fuel in an on-vehicle internal combustion engine. Ammonia is stored as, for example, a ligand in an on-vehicle transition metal composition. Upon demand for hydrogen by the vehicle's engine control system, ammonia is expelled as a gas from some of the composition and the ammonia gas is dissociated into a mixture of hydrogen and nitrogen and delivered as a fuel-containing mixture to the engine. In a preferred embodiment, the hydrogen is used as a supplement to gasoline as a fuel for engine operation.

Methods, systems, and apparatus for generating energy from a process-contained series of thermobaric reactions and/or explosion cycles are provided. The Xplogen™ energy generating system includes several embodiments for stimulating the heat and pressure release episodes, which are directed by the process system toward the task of dissociating a target substance being subjected to the hyper-stimulated pulse of energy. The target substance is thermolyzed by the pulse energy episode and the resulting dissociated gases are either quenched and captured or they are consumed in a direct thermal conversion process and are thus translated into steam pressure, and/or torque, thrust, motive force, and/or super-heat impulses. The methods and systems of the present invention include a comprehensive arrangement of process configurations and components as well as a means of operation.

A micromachined device for efficient thermal processing at least one fluid stream includes at least one fluid conducting tube having at least a region with wall thickness of less than 50 μm. The device optionally includes one or more thermally conductive structures in thermal communication with first and second thermally insulating portions of the fluid conducting tube. The device also may include a thermally conductive region, and at least a portion of the fluid conducting tube is disposed within the region. A plurality of structures may be provided projecting from a wall of the fluid conducting tube into an inner volume of the tube. The structures enhance thermal conduction between a fluid within the tube and a wall of the tube. A method for fabricating, from a substrate, a micromachined device for processing a fluid stream allows the selective removal of portions of the substrate to provide desired structures integrated within the device. As an example, the micromachined device may be adapted to efficiently react fluid reactants to produce fuel for a fuel cell associated with the device, resulting in a system capable of conversion of chemical to electrical energy.
摘要:
An improved metal gas separation membrane for separating hydrogen from a gas steam includes a quantity of metal particles that are bonded together to form a porous body that is selectively permeable to hydrogen. The porous body may have a porosity that increases from a first surface to an opposite second surface. The metal gas separation membrane may additionally include a coating of ceramic particles on the first surface thereof to further decrease the porosity at the first surface. Alternatively, or in addition thereto, the metal gas separation membrane may include a thin foil or coating of a dense precious metal such as palladium, palladium-alloys, and the like applied thereto that is permeable by hydrogen according to a chemisorption-dissociation-diffusion transport phenomenon. Still alternatively, or in addition thereto, the porous body may include a catalytic enhancement that can interact with a gas stream to increase the concentration of hydrogen according to various catalytic reactions such as the water gas shift reaction and the ammonia decomposition reaction.

摘要:
This method for hydrogen production from ammonia is based on the catalytic dissociation of gaseous ammonia in a cracker. A catalytic fixed bed is used. The ammonia cracker supplies a fuel cell (for example, an alkaline fuel cell AFC) with a mixture of hydrogen and nitrogen. Most of the supplied hydrogen is burned in the ammonia cracker for the supply of the energy needed for the ammonia dissociation process.
