Abstract

See full text

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.
