Abstract: A reactor system for carrying out an endothermic catalytic chemical reaction in a given temperature range upon bringing a reactant into contact with a catalyst material. The reactor system includes a reactor unit arranged to accommodate catalyst material including one or more ferromagnetic macroscopic supports susceptible for induction heating where the one or more ferromagnetic macroscopic supports are ferromagnetic at temperatures up to an upper limit of the given temperature range. The one or more ferromagnetic macroscopic supports are coated with an oxide, and the oxide is impregnated with catalytically active particles. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalyst material is heated to a temperature within the temperature range by the alternating magnetic field.

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.

Abstract: In a process for steam reforming of oxygenates, especially at low steam-to-carbon (S/C) ratios, a feed gas containing oxygenates, such as ethanol, is converted into syngas over a ternary carbide catalyst. Then the reformed gas is either transformed into desired chemicals or mixed into the feed stream to the reformer in a plant, such as an ammonia or methanol plant. The preferred ternary carbide is nickel zinc carbide.

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.
