    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: A system for production of a synthesis gas, including: a synthesis gas generation reactor arranged for producing a first synthesis gas from a hydrocarbon feed stream; a post converter including a catalyst active for catalyzing steam methane reforming, methanation and reverse water gas shift reactions; the post converter including a conduit for supplying a CO2 rich gas stream into a mixing zone of the post converter, where the CO2 rich gas stream in the conduit upstream the mixing zone is in heat exchange relationship with gas flowing over the catalyst downstream the mixing zone; a pipe combining the at least part of the first synthesis gas and the CO2 rich gas stream to a mixed gas, in a mixing zone being upstream the catalyst; wherein the post converter further includes an outlet for outletting a product synthesis gas from the post converter. Also, a corresponding process.

    Abstract: A reactor system for aromatization of higher hydrocarbons within a given temperature range T upon bringing a reactant stream including higher hydrocarbons into contact with a catalytic mixture. The reactor system includes a reactor unit arranged to accommodate a catalytic mixture. The catalytic mixture includes a catalyst material and a ferromagnetic material. The catalyst material is arranged to catalyze the aromatization of higher hydrocarbons. The ferromagnetic material is ferromagnetic at least at temperatures up to an upper limit of the given temperature range T, where the temperature range T is the range from between about 400° C. and about 700° C. or a subrange thereof. The reactor system also includes an induction coil arranged to be powered by a power source supplying alternating current, whereby the ferromagnetic material is heated to a temperature within the temperature range T by means of an alternating magnetic field.
