    摘要： An object of the invention is a recirculated solid oxide electrolyzer cell system, a cell comprising a fuel side (100), an oxygen rich side (102), and an electrolyte element (104) between the fuel side and the oxygen rich side. The system comprises at least one supersonic ejector (120) configured for recirculating (109) a fraction of gas exhausted from the fuel side (100) of each cell and for providing a desired recirculation flow rate of recirculated flow, the ejector having at least one nozzle (122); means (124) for providing at least one primary feedstock fuel fluid to said nozzle of the ejector (120), which nozzle has a convergent-divergent flow channel through which the fluid will expand from an initial higher pressure to a lower pressure; wherein the ejector (120) and possible sources of leakage are contained within structures (144) conveying non-explosive reactant to form leakage and explosive safe structure, and the system comprises a nested arrangement for at least one feed-in route (124) and an exhaust route, the arrangement being nested within the structure (144) conveying non-explosive reactant, and a trim heater (148) arranged within the structures (144) to provide heat to both fuel side (100) and oxygen rich side (102) flows.

    摘要： Process for producing methane or methanol, said process comprising the steps of: i) conducting a solid renewable feedstock to a thermal decomposition step, this being a pyrolysis step or a hydrothermal liquefaction step, for producing: a first off-gas stream comprising hydrocarbons, a solid carbon stream, and optionally a first liquid oil stream; upgrading the first off-gas stream by conducting it to a hydro/deoxygenation (HDO/DO) step i.e. hydrodeoxygenation or deoxygenation step in which said HDO/DO step is conducted in the absence of steam, and a subsequent separation step, for generating water, a second liquid oil stream and an upgraded first off-gas stream; ii) conducting the first off-gas stream or the upgraded first off-gas stream to an olefin removal step, for generating a further upgraded first off-gas stream which is free of olefins; iii-1) conducting the first off-gas stream, or the upgraded first off-gas stream, or the further upgraded first off-gas stream, to a methanation step under the generation of steam for producing said methane; or iii-2) conducting the first off-gas stream, or the upgraded first off-gas stream, or the further upgraded first off-gas stream, to a steam reforming step for producing a methanol synthesis gas and subsequently conducting the methanol synthesis gas to a methanol synthesis step under the generation of steam for producing said methanol; iv) conducting steam, such as at least a portion of the steam generated in step iii-1) or iii-2), to an electrolysis step for producing an oxygen stream and a hydrogen stream; v) conducting at least a portion of the hydrogen stream from the electrolysis step to any of the: thermal decomposition step including HDO-step, olefin hydrogenation step, methanation step, methanol synthesis step, or combinations thereof.

    摘要： Herein discussed is a method of producing hydrogen comprising: providing a tubular reactor having an open end and a closed end, wherein the reactor comprises an anode on the inside and a cathode on the outside separated by and in contact with a mixed conducting electrolyte, wherein the electrolyte comprises an electronically conducting phase and an ionically conducting phase, wherein the reactor comprises no current collector or interconnect; introducing a hydrocarbon and an oxidant into a feed tube, wherein the feed tube contains a catalyst that promotes catalytic partial oxidation (CPOX) reactions, wherein the feed tube extends into the open end of the reactor and toward the closed end of the reactor; introducing steam to the outside of the tubular reactor; and converting steam to hydrogen electrochemically without electricity input.

    摘要： An electrochemical cell includes a metal substrate and a cell body. The metal substrate has: a gas-permeable region in which a plurality of connecting holes are formed; and a non-gas-permeable region surrounding the gas-permeable region in a plan view. The cell body is disposed on the metal substrate. The cell body has: a first electrode layer containing Ni; a second electrode layer; and an electrolyte layer disposed between the first electrode layer and the second electrode layer. The first electrode layer has a first region formed on the gas-permeable region, and a second region formed on the non-gas-permeable region. A mean particle diameter of Ni contained in the second region is smaller than a mean particle diameter of Ni contained in the first region.
