A reactor includes an essentially horizontal cylinder for carrying out an autothermal gas-phase dehydrogenation of a hydrocarbon-comprising gas stream using an oxygen-comprising gas stream to give a reaction gas mixture over a heterogeneous catalyst configured as monolith. The interior of the reactor is divided by a detachable, cylindrical or prismatic housing, which is arranged in the longitudinal direction of the reactor and is gastight in the circumferential direction, into an inner region having one or more catalytically active zones, each having a packing composed of monoliths stacked on top of one another, next to one another and behind one another and before each catalytically active zone in each case a mixing zone having solid internals are provided and into an outer region, which is supplied with an inert gas, arranged coaxially to the inner region. A heat exchanger is connected to the housing at one end of the reactor.

Reactor for carrying out an autothermal gas-phase dehydrogenation

The invention relates to a reactor for carrying out an exothermic reaction in the gas phase, which comprises a vessel having an outer wall () composed of a metallic material, wherein an inner shell () is accommodated in the interior of the reactor () and the inner shell () has a spacing of at least 50 mm to the inside of the outer wall ().

Reactor for carrying out an exothermic reaction in the gas phase

A reactor in the form of an essentially horizontal cylinder for carrying out an autothermal gas-phase dehydrogenation of a hydrocarbon-comprising gas stream by means of an oxygen-comprising gas stream to give a reaction gas mixture over a heterogeneous catalyst configured as monolith is disclosed herein. The interior of the reactor is divided by a detachable, cylindrical or prismatic housing which is arranged in the longitudinal direction of the reactor, gastight in the circumferential direction and open at two end faces of the housing into an inner region, having one or more catalytically active zones. In each case, a packing composed of monoliths may be stacked on top of one another, next to one another, and above one another and before each catalytically active zone. Also in each case, a mixing zone having solid internals and an outer region arranged coaxially to the inner region are provided.
