Reactor for endothermic high-temperature reactions

A reactor for carrying out an endothermic reaction, in particular a high-temperature reaction, in which a product gas is obtained from a feed gas, wherein the reactor surrounds a reactor interior, wherein the reactor is configured to provide a gravity-driven moving bed in a reaction zone of the reactor interior, which moving bed comprises a large number of solid material particles, wherein the reactor is also configured to guide the feed gas into the reaction zone, wherein, in order to heat the feed gas, the reactor is configured to heat the solid material particles in the reaction zone by generating an electric current in the solid material particles such that, by transferring heat from the solid material particles to the feed gas, the feed gas in the reaction zone can be heated to a reaction temperature in order to participate as a starting product in the endothermic reaction for producing the product gas, and wherein the reactor interior also comprises a first heat integration zone in which heat from the product gas produced in the reaction zone can be transferred to solid material particles of the reactor bed which are to be guided into the reaction zone, and wherein the reactor interior also comprises a second heat integration zone in which heat from solid material particles of the reactor bed coming from the reaction zone can be transferred to the feed gas in order to preheat the feed gas.
