摘要： 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.

摘要： A reactor system for dehydrogenation of ethylbenzene to styrene in a given temperature range T upon bringing a reactant stream including ethylbenzene into contact with a catalytic mixture. The reactor system includes a reactor unit arranged to accommodate the catalytic mixture, the catalytic mixture including catalyst particles in intimate contact with a ferromagnetic material, where the catalyst particles are arranged to catalyze the dehydrogenation of ethylbenzene to styrene. 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 catalytic mixture is heated to a temperature within the temperature range T by means of the alternating magnetic field. Also, a catalytic mixture and a method of dehydrogenating ethylbenzene to styrene.

摘要： A reactor system for dehydrogenation of alkanes in a given temperature range upon bringing a reactant stream including alkanes into contact with a catalytic mixture. The reactor system includes a reactor unit arranged to accommodate the catalytic mixture, where the catalytic mixture includes catalyst particles and a ferromagnetic material. The catalyst particles are arranged to catalyze the dehydrogenation of alkanes. The ferromagnetic material is ferromagnetic at least at temperatures up to an upper limit of the given temperature range. 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 catalytic mixture is heated to a temperature within the temperature range by means of the alternating magnetic field. Also, a catalytic mixture and a method of dehydrogenating alkanes.
