Abstract: An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.

Abstract: A chemical reactor for use in a chemical process wherein a reactant and/or a target product is prone to produce undesirable byproducts through secondary reactions. The reactor is configured with a first flow passage for passing a flow of an overly reactive reactant; a permeable first wall for controlled flow of the overly reactive reactant into a second flow passage providing a flow of a second reactant; a permeable second wall having a catalyst supported on an inner surface thereof for catalyzing reaction of the reactants flowing in the second flow passage; the permeable second wall passing through a flow containing the target product; and a non-permeable third wall defining a third flow passage for exiting the product mixture. The reactor can be employed in selective oxidation, oxidative dehydrogenation, and alkylation processes to reduce the formation of byproducts.

Abstract: A spark-ignited (SI) internal combustion (IC) engine designed to operate on high octane fuels, such as gasoline, is reconfigured to operate on low octane fuels including logistically preferred distillate fuels, such as diesel or JP-8. Design modifications involve coupling a fuel reformer module to the internal combustion engine. Auxiliary components include a system control module, a heat exchange module, a bypass valve to facilitate start-up, and/or a throttle body to control a reformate-oxidizer mixture fed to the engine. Small portable generators having 0.3-3.0 kWe power output are disclosed based upon the modified SI-IC engine design.

Abstract: A novel catalytic reactor is provided for controlling the contact of a limiting reactant with a catalyst surface. A first flow vessel defines an interior surface and an exterior surface, and the interior surface has a catalyst deposited on at least a portion thereof. A second flow vessel is positioned within the first flow vessel and the second flow vessel defines a porous surface designed to deliver a fluid uniformly to at least a portion of the interior surface of the first flow vessel.

Abstract: A catalytic solar reactor useful in chemical processes, more particularly, useful in endothermic chemical processes. The reactor comprises a reaction pathway defined by an exterior wall and an interior wall, the exterior wall comprising a solar radiation receiver capable of converting solar radiation into heat and transmitting the heat to the reaction pathway. Further, the reaction pathway has disposed therein, in alternating fashion, a plurality of catalytic elements and a plurality of heat transfer elements. Optionally, a supplementary heater, such as a conventional fossil fuel burner, is disposed in a plenum located within the interior of the reactor. The heater is employed as a supplemental source of heat, for example, when solar radiation is unavailable.

Abstract: A solid sorbent composition including calcium oxide, calcium aluminate, and a mixed metal oxide characterized by a perovskite crystalline structure, for example, lanthanum aluminate. The solid sorbent finds utility in capturing carbon dioxide from a gaseous stream containing carbon dioxide, such as emissions streams produced in combustion processes or streams derived from closed environments including airplanes, spaceships, and submarines. A reversible carbon dioxide process is disclosed involving (a) contacting a carbon dioxide-containing gaseous stream with the solid sorbent composition in a carbonator to produce a solid mixture containing calcium carbonate and a gaseous product stream reduced in carbon dioxide concentration; and (b) heating the solid mixture containing calcium carbonate in a calcinator (decarbonator) to regenerate the solid sorbent composition and produce a gaseous stream enriched in carbon dioxide.

Abstract: An integrated power generation system including: a hotbox containing a steam reformer and at least one solid oxide fuel cell (SOFC) stack; a condenser, a combustor, a heater, and a turbomachine comprising a compressor and an expander. The steam reformer is configured to convert a hydrocarbon fuel and steam into a stack fuel. The SOFC stack is configured to convert the stack fuel into a first anode waste gas. The condenser functions to remove water from the first anode waste gas, thereby producing a second anode waste gas of higher fuel energy density. The combustor bums the second anode waste gas with release of exothermic heat. The heater thermally transmits heat from an expanded combustion product to water collected in the condenser, so as to generate steam. A steam line fluidly connects the heater to the steam reformer.

Abstract: A process and apparatus for converting an alkane to an olefin. In one embodiment, the process involves oxidative coupling of an alkane, e.g., methane, with an oxidant, such as air, to produce an olefin having twice the number of carbon atoms as the alkane, e.g., ethylene. In another embodiment, the process involves oxidative dehydrogenation of an alkane, e.g., ethane, with an oxidant to form an olefin having the same number of carbon atoms as the alkane, e.g., ethylene. The process involves passing a flow of the oxidant from a first flow passage through a porous medium; diffusing a flow of the alkane from a second flow passage into the porous medium; and contacting the reactant alkane and the oxidant in the presence of a catalyst within the porous medium to produce the olefin.
