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: In a process for the catalytic conversion of lower hydrocarbons to aromatic compounds comprising benzene, toluene and xylenes, a process stream containing lower hydrocarbons is contacted with a zeolitic catalyst having an MFI framework and containing 0.1 to 10 percent by weight of a zinc compound. The process stream further contains one or more sulfur compounds, especially hydrogen sulfide, for improving the selectivity.
