1. A reactor system for carrying out an endothermic reaction of a feed gas, said reactor system comprising:
a structured catalyst arranged for catalyzing said endothermic reaction of said feed gas, said structured catalyst comprising a macroscopic structure of electrically conductive material, said macroscopic structure supporting a ceramic coating, wherein said ceramic coating supports a catalytically active material;
a pressure shell housing said structured catalyst;
a heat insulation layer between said structured catalyst and said pressure shell; and
at least two conductors electrically connected to said structured catalyst and to an electrical power supply placed outside said pressure shell, wherein said electrical power supply is dimensioned to heat at least part of said structured catalyst to a temperature of at least 200° C. by passing an electrical current through said electrically conductive material,
wherein the pressure shell comprises an inlet at a first end of the pressure shell for letting in process gas and an outlet at a second end of the pressure shell for letting out product gas, and wherein the at least two conductors are connected to the structured catalyst at a position closer to the inlet than to the outlet.
