Abstract: 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.

Abstract: In a process for the elimination of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) formed as by-products in the shift section (SS) of an ammonia plant, a carbon dioxide (C02) stream from a vent line, which is arranged downstream from the shift section and the C02 removal section, is recycled to the primary reformer (TR) of the ammonia plant. This way, the oxygenates contained in the carbon dioxide vent will be decomposed in the primary reformer burners, and the total emission of VOCs and HAPs will be considerably reduced.
