摘要： The present disclosure relates to a power production system that is adapted to achieve high efficiency power production using partial oxidation of a solid or liquid fuel to form a partially oxidized stream that comprises a fuel gas. This fuel gas stream can be one or more of quenched, filtered, and cooled before being directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle CO2 stream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The expanded and cooled exhaust stream can be further processed to provide the recycle CO2 stream, which is compressed and passed through one or more recuperator heat exchangers in a manner useful to provide increased efficiency to the combined systems.

摘要： A fuel cell system is disclosed. The fuel cell system comprises: a fuel cell module including a plurality of unit cells for generating electrical energy by using oxygen of air and hydrogen of a reformed fuel gas; a first module including a burner part which burns an unreacted fuel gas and air discharged from the fuel cell module, an air-heating part which heats air through heat exchange with a hot combustion gas and a flame generated by the burner part and supplies the heated air to the fuel cell module, and a water vapor generation part which converts water, flowing through an inner portion thereof, into water vapor through heat exchange with a hot combustion gas generated by the burner part; and a second module which mixes a fuel supplied from an external fuel supply source and water vapor supplied from an water-vapor generator part, allows a water vapor reformation reaction to occur, and supplies a reformed fuel gas to the fuel cell module.

摘要： An enhanced natural gas processing method using Fischer-Tropsch (FT) process for the synthesis of sulfur free, clean burning, hydrocarbon fuels, examples of which include syndiesel and aviation fuel. A selection of natural gas, separately or combined with portions of natural gas liquids and FT naphtha and FT vapours are destroyed in a syngas generator and used or recycled as feedstock to an Fischer-Tropsch (FT) reactor in order to enhance the production of syndiesel from the reactor. The process enhancement results are the maximum production of formulated syndiesel without the presence or formation of low value by-products.

摘要： Systems and methods are provided for hydrogenation of CO2 in a reverse flow reactor environment via a reverse water gas shift reaction. A reverse flow reactor environment is suitable for performing endothermic reactions at high temperatures, where a reactant flow is passed into the reactor in a first portion of the cycle in a first flow direction while a combustion or heating flow is passed into the reactor during a second portion of the reaction cycle from the opposite direction. This can allow for efficient heating of surfaces within the reactor to provide heat for the endothermic reverse water gas shift reaction while reducing or minimizing incorporation of combustion products into the desired reaction products.

摘要： A reformer suitable for micro-scale design has horizontal catalyst tube(s) passing through a baffled radiant section for convective and radiant heat transfer to the tube(s). To reduce the footprint and/or to facilitate field assembly a combustion chamber and convection section can be oriented transversely with respect to the radiant section; the tube(s) can be horizontal and/or include structured catalyst; and/or the combustion chamber provides flameless combustion or produces a flame without impinging on the tubes. Also, a skid frame-mountable version of the reformer; and a process for transporting, assembling, and/or operating the steam methane reformer.
