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： An apparatus for carrying out a chemical reaction in a process fluid includes a reactor comprising one or more reaction tubes which have a number of electrically heatable tube segments which are connected to one another by an electrically conductive star bridge, and at least one power source configured to provide a multiphase alternating current with N phases to N phase lines at a predetermined voltage. N is an integer greater than or equal to 2. For each of the at least one power source, a number of power connections is provided, each of which is connected to at least one of the tube segments and to one of the phase lines of the power source. In the at least one power source, a star point is formed at which the phase lines of the power source are connected, wherein the star point is not connected to a ground connection.

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 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.
