Abstract: A method for regulatedly carrying out a chemical reaction in a reactor having reaction tubes which have a number of electrically heatable tube sections, wherein power connections are provided, which are each connected to at least one of the tube sections, wherein at least one connecting element is provided and each of the tube sections is connected to the connecting element. The method comprises conducting a process fluid through the one or more reaction tubes, providing several variable voltages at the several power connections, wherein the several voltages are provided as phases of a multiphase AC voltage so that the at least one connecting element forms a star point, setting the one or more voltages; detecting one or more measured values corresponding to one or more measured variables; changing the several set voltages so that the detected measured values correspond to predetermined values or value ranges of the measured variables.

Abstract: A reactor has a reactor vessel and a reaction tube. Tube sections of the reaction tube run inside the reactor vessel. The tube sections are each electrically connectable to a current connection in a current feed region. Current feed arrangements are arranged in the current feed region to which in each case one or one group of the tube sections is electrically connected. Each current feed arrangement has a first and a second section, the first section extending along a longitudinal axis starting from the respective or group of tube section(s). The first section at least partially surrounds the second section or the second section surrounds the first section in a sleeve-like manner. The first and second sections each have contact surfaces arranged obliquely to the longitudinal axis. The current feed arrangements each extend through a wall of the reactor vessel.
