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: A tube heat exchange reactor for carrying out an endothermic catalytic reaction. The tube heat exchange reactor includes: an outer tube with a first and a second end, where the first end is an inlet end and where the second end is a closed end, an inner tube coaxially arranged within the outer tube and spaced apart from the outer tube, where at least a part of the inner tube holds a bed of catalyst material susceptible for induction heating and where the inner tube has an inlet end and an outlet end, an induction coil placed within the annular space confined between the outer and the inner tube, and a power source arranged to supply alternating current to the induction coil in order to generate an alternating magnetic field within at least a part of the inner tube.

Abstract: In a process for the synthesis of a nitrile by endothermic catalyzed reaction of ammonia with a hydrocarbon using heating obtained by passing an alternating current through a metallic coil, the endothermic reaction between ammonia and the hydrocarbon takes place in a reactor with direct inductive heating in the reaction zone. The heating is extremely fast, which makes the reaction practically instantaneous.

Abstract: In a process for producing hydrogen or syngas by methanol cracking, whereby methanol is catalytically decomposed into hydrogen and carbon monoxide in an endothermal reaction, said reaction takes place in a reactor with direct inductive heating in the reaction zone. The heating is obtained by passing an alternating current through a metallic coil located inside the reactor or by using induction heated catalyzed hardware in the shape of a ferromagnetic structure, which is coated with an oxide impregnated with the catalytically active phase.

Abstract: A catalyst for the dehydrogenation of alkanes to alkenes comprises a catalytically active material supported on a carrier, wherein the catalytically active material is a metallic sulfide (MeS) comprising Fe, Co, Ni, Cu, Mo or W or any combination of two or more metals selected from Pb, Sn, Zn, Fe, Co, Ni, Cu, Mo and W. The catalyst is regenerated in several steps. The dehydrogenation is carried out at a temperature between 450 and 650° C. and a pressure from 0.9 bar below ambient pressure to 5 bar above ambient pressure.

Abstract: A catalyst for the dehydrogenation of alkanes to alkenes comprises lead(II) sulfide (PbS) as catalytically active material supported on a carrier. The dehydrogenation is carried out at a temperature between 500 and 650° C. and at a pressure from 0.5 bar below ambient pressure to 5 bar above ambient pressure.
