Abstract: 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.

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: 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.
