Abstract: A method for the generation of a gas mixture including carbon monoxide, carbon dioxide, and hydrogen for use in hydroformylation plants, including: evaporating water to steam; feeding the steam to a solid oxide electrolysis cell (SOEC) while supplying an electrical current to the SOEC to effect 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 by cooling the raw product gas stream allowing for condensation of at least part of the steam as liquid water and separating the remaining product gas from the liquid; using the gas mixture for liquid phase hydroformylation, while recycling CO2 to the RWGS reactor.

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: 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 the generation of syngas for use in hydroformylation plants comprises the steps of evaporating water to steam, mixing the steam with carbon dioxide in any desired molar ratio and feeding the resulting gas to a solid oxide electrolysis cell (SOEC) or an SOEC stack at around 700° C. while supplying an electrical current to the cell or cell stack to convert the feed gas to syngas. An advantage is that the syngas can be generated on the site where it is intended to be used.

Abstract: A method for the generation of a gas mixture comprising carbon monoxide, carbon dioxide and optionally hydrogen for use in hydroformylation plants or in carbonylation plants, including mixing an optional steam with carbon dioxide in the desired molar ratio, feeding the resulting gas 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 carbon dioxide to carbon monoxide and optionally of steam to hydrogen, removing some or all the remaining steam from the raw product gas stream by cooling the raw product gas stream and separating the remaining product gas from a liquid, and using said gas mixture containing CO and CO2 for liquid phase synthesis reactions utilizing carbon monoxide as one of the reactants while recycling CO2 to the SOEC or SOEC stack.
