摘要： 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.

摘要： A reactor for carrying out a chemical reaction using multiphase alternating current, includes a reactor chamber surrounded by thermally insulating reactor walls and multiple substantially straight reaction tubes. The reaction tubes run between at least one tube inlet opening and at least one tube outlet opening in opposite reactor walls and consist of a material that permits electrical resistance heating. Two electrically conductive bridges spaced apart along the reaction tubes are provided, each of which electrically conductively connects the reaction tubes to one another. Electrically conductive power input arrangements are provided extending through one or more input openings in one of the reactor walls. Each reaction tube is electrically conductively connected to one of the power input arrangements. Each power input arrangement is electrically conductively connected between the bridges to one of the reaction tubes and is connected or connectable to one of the phases of the alternating current.

摘要： Disclosed is a reactor for carrying out a chemical reaction and a corresponding method. The reactor includes a vessel and one or more reaction tubes where a number of tube sections of the reaction tubes run between first second regions in the reactor vessel, and where the tube sections in the first region for the electrical heating of the tube sections can be electrically connected to the phase connections of a polyphase AC power source. Tube sections in the second region are electrically and conductively connected to one another as a whole by means of a single rigid connecting element, or in groups by means of a plurality of rigid connecting elements which are integrally connected to the reaction tubes and are arranged inside the reactor vessel. A corresponding method is also the subject-matter of the present invention.

摘要： A reactor has a reactor vessel and one or more reaction tubes. One or more power input elements are guided into the reactor vessel for the electrical heating of the reaction tube(s). The one or more power input elements each have a rod-shaped section, and the rod-shaped section(s) each run in a respective wall passage through a wall of the reactor vessel. A connection chamber into which the rod-shaped section(s) project is arranged outside the reactor vessel and adjacent to the wall of the reactor vessel through which the rod-shaped section(s) run in their wall passages. Gas feed means apply an inerting gas to the connection chamber, and the wall passages with the rod-shaped sections received therein in a longitudinally-movable manner are designed to be gas-permeable so that at least a portion of the inerting gas fed into the connection chamber flows out into the reactor vessel.
