Abstract

A reactor for carrying out a continuous oxydehydrogenation of a feed gas stream of saturated hydrocarbons after premixing with an oxygen-comprising gas stream over a moving catalyst bed which is introduced in the longitudinal direction of their reactor between two concentric cylindrical holding devices so as to leave a central interior space and an intermediate space between the moving catalyst bed and the interior wall of the reactor to give a reaction gas mixture, wherein the reactor has two or more reactor sections which are separated from one another by disk-shaped deflection plates arranged alternately in the central interior space and divided in subregions by annular deflection plates arranged in the intermediate space between the moving catalyst bed and the interior wall of the reactor, in each case with a mixing-in device which is located upstream of the moving catalyst bed in the flow direction of the reaction gas mixture and comprises the following elements:
