Beschreibung
Zusammenfassung:	The invention relates to a reactor (1) in the form of a cylinder with a vertical longitudinal axis, for performing an autothermal gas-phase dehydrogenation of a hydrocarbon-containing gas stream (2) with an oxygen-containing gas stream (3), obtaining a reaction gas mixture, on a heterogeneous catalyst, which is designed as monolith (4), wherein one or more catalytically active zones (5) are arranged in the interior of the reactor (1), each zone comprising a packing of monoliths (4) stacked one next to another and/or one on top of another and wherein a mixing zone (6) with fixed installations is provided upstream of each catalytically active zone (5). The reactor has: - one or more feeder lines (7) at the lower end thereof for the hydrocarbon-containing gas stream (2) to be dehydrogenated; - one or more feeder lines (9) that can be regulated independently of one another for the oxygen-containing gas stream (3) flowing into each of the mixing zones (6), each feeder line (9) feeding one or more distributors (10);; - and one or more discharge lines (11) at the upper end of the reactor (1) for the reaction gas mixture from the autothermal gas-phase dehydrogenation, wherein the interior wall of the reactor (1) is furnished with a continuous insulation layer (13, 14, 15) and wherein the accessibility of one or each of the plurality of catalytically active zones (5) from outside the reactor is guaranteed via - one or more manholes (12), or wherein one or each of the plurality of catalytically active zones (5), each comprising a respective packing of monoliths stacked one next to another and/or one on top of an other including - the mixing zone (6) with fixed installations provided upstream of each catalytically active zone (5) - the one or more feeder lines (9) controllable independently of one another - and the one or more distributors (10) that are each fed via a respective feeder line (9),; are constructed as a structural element (24) that can be individually installed or uninstalled.
