Abstract: A heat pump that includes organic hydride (12) and metal hydride (2) systems cools a conditioned space (6) by transferring heat from the conditioned space to a metal hydride bed (4), thereby decomposing a metal hydride in the bed to form H2. The H2 flows to a vapor space (14) in the liquid hydride system (12) and reacts with a dehydrogenation product at a catalytic surface (32) in the vapor space to form an organic hydride and an exothermic heat of reaction. The heat pump also may be used to upgrade waste heat by transferring heat from a relatively low temperature heat source to decompose the metal hydride. The exothermic heat of reaction may then be removed from the vapor space and used for space heating. In both embodiments, the metal hydride bed (4) may be regenerated by supplying an endothermic heat of reaction to the catalytic surface (32), thereby dehydrogenating the organic hydride to form H2. The H2 flows to the metal hydride bed (4) and reacts with the metal hydride bed to regenerate the metal hydride. Alternately, the metal hydride bed (4) may be regenerated by flowing a liquid mixture that includes the organic hydride into a reaction zone (38) having a dehydrogenation catalyst (42) and supplying an endothermic heat of reaction to the reaction zone, thereby dehydrogenating the organic hydride to form H2. As before, the H2 flows to the metal hydride bed (4) where it regenerates the metal hydride.

Abstract: A method of combusting a hydrocarbon fuel includes mixing the fuel with a first air stream to form a fuel/air mixture having an equivalence ratio of greater than 1 and partially oxidizing the fuel by contacting it with an oxidation catalyst to generate a heat of reaction and a partial oxidation product stream. The partial oxidation product stream is mixed with a second air stream and completely combusted in a main combustor at a condition at which appreciable quantities of thermal NOx are not formed to generate an effluent gas stream, thereby generating an effluent gas stream containing decreased amounts of thermal and prompt NOx. A system for combusting a hydrocarbon fuel includes, in combination, means for mixing the fuel with a first air stream, a catalytic oxidation stage containing an oxidation catalyst, means for mixing the partial oxidation product stream with a second air stream, and a main combustor capable of completely combusting the partial oxidation product stream.

Abstract: A cooling device cools a conditioned space (6) by transferring heat from the conditioned space to a working fluid (2) in a heat exchanger (4). A compressor (10) compresses the working fluid (8), which is then condensed in a condenser (14). Heat from the condenser is transferred to dehydrogenation reaction zone (104) that includes dehydrogenation catalyst (106) to supply a portion of an endothermic heat of reaction. The catalyst (106) is contacted with an organic hydride (102) to dehydrogenate the organic hydride to form H2 (108) and at least one dehydrogenation product (110). A combustor (112) burns the H2 (108) to form combustion products (114) that expand in a turbine (116) to drive the compressor (10). A portion of the heat of combustion is used to supply the remainder of the endothermic heat of reaction required in the dehydrogenation reaction zone (104).

Abstract: A method of combusting an endothermic fuel in a lean premixed/prevaporized combustion system includes transferring thermal energy from a combustion air stream to an endothermic fuel decomposition catalyst to cool the combustion air stream and heat the fuel and catalyst to a temperature sufficient to endothermically decompose an endothermic fuel. The catalyst is contacted with fuel to cause the fuel to endothermically decompose into a reaction product stream. The reaction product stream is mixed with the cooled combustion air stream to form a well-mixed, uniformly lean fuel/air mixture and the fuel/air mixture is combusted at an equivalence ratio of less than 1 to produce a combustion product stream. The invention also includes a system for practicing the method.

Abstract: Gas Transporting System A first gas produced or supplied at a first location is reacted (combined) with a selected reactant in a reversible chemical reaction to produce a gaseous reaction product which is converted to liquid-form and conveyed, as a liquid, to a second location remote from the first location, whereupon it is converted back to its original gaseous constituents in a chemical reaction the reverse of the initial reaction. The regenerated first gas, now at the second location, is separated from the regenerated reactant which is returned to the first location to be used again.
