Abstract

A reactor for gas-phase dehydrogenation of a hydrocarbon-comprising stream with an oxygen-comprising stream over a monolithic heterogeneous catalyst. Catalytically active zone(s) comprising monoliths packed next to one another and/or above one another and a mixing zone having fixed internals upstream of each catalytically active zone. Feed line(s) for the hydrocarbon-comprising gas stream to be dehydrogenated at the lower end of the reactor. Independently regulable feed line(s), which supply distributor(s), for the oxygen-comprising gas stream into each of the mixing zones and discharge line(s) for the reaction gas mixture of the autothermal gas-phase dehydrogenation at the upper end of the reactor. The interior wall of the reactor is provided with insulation. The catalytically active zone(s) is accessible from the outside of the reactor via manhole(s). The catalytically active zone(s), mixing zone, independently regulable feed line(s), and distributor(s), may be designed as one component which can individually be mounted and removed.
