Abstract
Apparatus, in particular reactor for carrying out endothermic catalytically promoted gas-phase reactions, which has, arranged one on top of the other or one inside the other in a common jacket, a tube-bundle heat exchanger 1 consisting of a plurality of parallel tubes provided with baffles 1a securing a flow of the heat exchanging medium in a direction transverse to the axis of said tubes, a reaction space 6 which preferably widens conically upward, has a base and is intended for holding a catalyst bed, a tube-bundle heat exchanger 2 to which material flows laterally and which is provided with baffles 2a, a reaction space 4 which has a base, is closed at the top by a gas dome and is intended for holding a catalyst bed, a central tube 3 for connecting the outer space of the heat exchanger 1 to the gas space above the reaction space 4, and inlet and outlet means for a heating or cooling gas (c) and inlet and outlet means (a or b) for the fresh gas or reaction mixture, respectively.
