Abstract: The invention relates to a method for autothermal gas phase dehydrogenation of a hydrocarbon-containing gas stream (2) with an oxygen-containing gas stream (3), obtaining a reaction gas mixture in the presence of a heterogeneous catalyst which is constructed as a monolith (4), and regeneration of the catalyst in a reactor (1) in the form of a cylinder or prism, wherein: - the interior of the reactor (1) is subdivided by a plain cylindrical or prismatic gas-tight housing (G) that is arranged in the longitudinal direction of the reactor (1) into; - an internal region A and; - an external region B arranged coaxially to the internal region A, which is characterized in that the reactor is operated alternately in the production mode for the autothermal gas phase dehydrogenation, and in the regeneration mode, wherein: - the production mode for the autothermal gas phase dehydrogenation is run until the temperature elevation of the reaction gas mixture on exit of same from the discharge line (11) does not exceed 5 K, based on the time point from which the conversion rate fluctuates by no more than 1%, based on the final conversion rate, whereupon; - the reactor is switched into the regeneration mode, with supply of an inert regeneration gas which contains at least 10% by weight oxygen, based on the total weight of the regeneration gas.

Abstract: The invention relates to a method for electrochemically removing hydrogen from a hydrogen-containing reaction mixture R by means of a gas-tight membrane electrode assembly which comprises at least one selectively proton-conducting membrane and at least one electrode catalyst on each side of the membrane, at least part of the hydrogen contained in the reaction mixture R being oxidized on the anode catalyst to protons on the retentate side of the membrane and the protons, after passing the membrane and on the permeate side on the cathode catalyst, I being reduced to hydrogen and/or II being reacted with oxygen to water, the oxygen coming from an oxygen-containing flow O which is being contacted with the permeate side of the membrane. The invention further relates to a reactor which is equipped with at least one membrane electrode assembly.
