Abstract: A method for the generation of a gas mixture including carbon monoxide, carbon dioxide and hydrogen for use in hydroformylation plants, including the steps of evaporating water to steam; feeding the steam to a solid oxide electrolysis cell (SOEC) or an SOEC stack at a sufficient temperature for the cell or cell stack to operate while effecting a partial conversion of steam to hydrogen; utilizing the effluent SOEC gas including H2 together with CO2 from an external source as feed for a RWGS reactor in which the RWGS reaction takes place, converting some of the CO2 and H2 to CO and H2O; removing some of or all the remaining steam from the raw product gas stream; using said gas mixture comprising CO, CO2 and H2 for liquid phase hydroformylation utilizing carbon monoxide and hydrogen as reactants, while recycling CO2 to the RWGS reactor.

Abstract: A method for coating an interconnect for a solid oxide cell (SOC) stack comprises providing an interconnect substrate comprising Cr and Fe, coating the interconnect substrate with a first metallic layer by electrodeposition, coating the resulting structure with a second layer of metallic cobalt by electrodeposition and coating the resulting structure with a layer of metallic copper by ion-exchange plating. This way, a metallic copper-cobalt coating is formed on the interconnect.

Abstract: In a method for chromium upgrading of interconnects made of ferritic steel to be used in solid oxide cell stacks, comprising the steps of shaping the interconnect, depositing a coating comprising Cr on at least one surface of the shaped interconnect and performing one or more thermal treatments at a temperature below 1000° C., the resulting Cr concentration near the surface of the interconnect is higher than the Cr concentration in the ferritic steel before shaping. Specifically, the average Cr concentration of the shaped interconnect is increased to 26 wt % Cr or higher.

Abstract: The content of oxygen in molten metallic copper is reduced during the copper refining process by adding pure carbon monoxide, produced by electrolysis of carbon dioxide in a solid oxide electrolysis cell (SOEC), thereby removing oxygen through the reduction of CuO to Cu. This way, the purity of the metallic copper is increased.

Abstract: A Solid Oxide Electrolysis System has electrolytes with increased Area Specific Resistance, ASR yet is thin as compared to known electrolytes in the field, to obtain heating of the endothermic reducing process performed in the electrolysis cells directly where it is needed without any extra heating appliances or integrated heating elements, a simple efficient solution which does not increase the volume of the stack.
