TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The body is applied with a torque for the rotation of the body by a driving device, preferably electric motor or a turbine impeller. The driving device is arranged in the reactor vessel. The driving device is arranged outside the reactor vessel, and the torque is transmitted through a vessel wall by a magnetic coupling. The turbine impeller is operated with exhaust gas of the load. The movably mounted body is formed as a diagonal- and/or a radial compressor, which is provided on its outer contour with a covering strip internally coated with the catalyst. The covering strip at its inner side flooded with the LOHC and/or the carrier during the rotation is provided with grooves or porous, preferably sponge-like structures, platforms arranged in a cascaded manner or ridges. A flow-guiding device, preferably radial or axial guiding ring with several guiding blades is arranged inside the reactor vessel, where the media flow, preferably gas flow, preferably hydrogen gas flow emerging from the body is flown. The reactor vessel around the outlet region of the carrier material of the body or the covering strip is constructed as fluid-mechanically shaped collecting spiral with an exit point for transferring into the discharge line, so that the exit point is arranged at a local low point of the vessel interior, or in such a manner that the exit point is constructed as an outlet diffuser. The reactor vessel around the outlet region of the gases from the body is constructed as the fluid-mechanically shaped collecting spiral with the exit point for transferring into the connecting line, so that the exit point is arranged at a local high point of the reactor vessel interior, or in such a manner that the exit point is constructed as the outlet diffuser. An additional body, preferably compressor impeller provided with the covering strip, mounted in movable, preferably rotating manner, is arranged in the reactor vessel, where the additional body is connected with the body in a torque-resistant manner, and the arrangement as a common rotor-runner and the separate area sealed to the interior of the reactor vessel are provided with separate access opening, preferably channel conducting intake air, and open in the region of the exit of gas exit on the body. The body exhibits a hollow and driving shaft conducting out from the reactor, which supplies the intake air from the outside. The movably mounted body or the covering strip is provided with additional flow channels running radially or conducting ridges. The wall of the reactor vessel is constructed with at least one heat transfer medium leading cavity, preferably flow channel. The reactor vessel is equipped at least partially with a thermal insulation at its outside. The reactor vessel and the heat exchanger are integrated.
