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: A non-porous membrane (64) suitable for use in removing dissolved oxygen in a fuel deoxygenator device in an aircraft is produced by solvent casting. A first membrane layer (66) is deposited on a substrate (78). A second membrane layer (68) is deposited on top of the first membrane layer (66). Subsequent membrane layers may be deposited on top of the second membrane layer (68) as desired. The resulting non-porous membrane (64) allows little or no leaking of fuel across the membrane.

Abstract: A fuel system for an energy conversion device includes a deoxygenator system (14) with a porous membrane. The deoxygenator includes an oxygen receiving channel (40) separated from the fuel channel (38) by the porous membrane (36). The capillary forces counteract the pressure differential across the membrane, preventing any leakage of the fuel, while the oxygen concentration differential across the membrane allows for deoxygenation of the fuel through the porous membrane.

Abstract: A fuel system for an energy conversion device includes a deoxygenator system with a multitude of flow impingement elements which are interleaved t o provide a fuel channel with intricate two-dimensional flow characteristics. The flow impingement elements break up the boundary layers and enhance the transport of oxygen from the core of the of the fuel flow within the fuel channel to the oxygen permeable membrane surfaces by directing the fuel flow in a direction normal to the oxygen permeable membrane. The rapid mixing of the relatively rich oxygen co re of the fuel with the relatively oxygen-poor flow near the oxygen permeable membrane enhances the overall removal rate of oxygen from the fuel. Because this process can be accomplished in fuel channels of relatively larger flow areas while maintaining laminar flow, the pressure drop sustained is relatively low.

Abstract: A deoxygenator includes a plurality of permeable membranes spirally wou nd about an exhaust tube for removing dissolved oxygen from a hydrocarbon fuel. The permeable membrane is spirally wrapped about the exhaust tube and defines fu el passages and exhaust passages. The fuel passages and exhaust passages alternate such that each fuel passage is bounded on each adjacent side by an exhaust passage. An oxygen partial pressure differential is generated across the permeable membrane to draw dissolved oxygen from fuel in the fuel passage. The dissolved oxygen is then communicated through openings about the circumference of the exhaust tu be and out the deoxygenator.

Abstract: A fuel system for a propulsion system includes a fuel deoxygenating device a nd a catalytic module containing catalytic materials. The fuel deoxygenating device removes dissolved oxygen from the fuel to prevent formation of insoluble materials that can potentially foul the catalyst and block desirable catalytic reactions th at increase the usable cooling capacity of an endothermic fuel.
