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 Htogether with COfrom an external source as feed for a RWGS reactor in which the RWGS reaction takes place, converting some of the COand Hto CO and HO; removing some of or all the remaining steam from the raw product gas stream; using said gas mixture comprising CO, COand Hfor liquid phase hydroformylation utilizing carbon monoxide and hydrogen as reactants, while recycling COto the RWGS reactor.

Method for generating synthesis gas for use in hydroformylation reactions

In a process for safe production of phosgene (COCI) from carbon monoxide and chlorine according to the reaction scheme CO (g)+Cl(g)&#x2212;&#x3e;COCI(g) in a plant with a capacity of phosgene below 10 t/hr, the CO is produced on site from a feed stock based mainly on CO. The plant preferably comprises a solid oxide electrolysis cell (SOEC) stack system producing CO for use together with chlorine in the phosgene synthesis. This way of producing phosgene is based on using primary raw materials for which escape concentrations above 1000 ppm or even above 10000 ppm or 10% will not result in any health risk.
