A VENEERED ELEMENT AND METHOD OF PRODUCING SUCH A VENEERED ELEMENT

摘要

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.
