A reactor includes a reactor vessel and one or more reaction tubes A number of tube sections of the one or more reaction tubes in each case run between a first region and a second region in the reactor vessel. For the electrical heating of the tube sections, the tube sections in the first region can be electrically connected to (a) current connection(s) of a current source. In the first region, current feed arrangements are provided; in each case one or in each case one group of the tube sections are electrically connected, and each comprise (a) contact passage(s) that in each case adjoin(s) at least one of the tube sections in the first region. A wall of the contact passages in each case is connected to a current feed element that has a rod-shaped section that runs at a wall passage through a wall of the reactor vessel.

Reactor and method for carrying out a chemical reaction

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.

A reactor for carrying out a chemical reaction has a reactor vessel, one or more reaction tubes and means for the electrical heating of the one or more reaction tubes. The reactor vessel has one or more discharge orifices which are permanently open or are set up to open above a preset pressure level, and gas feed means are provided, which are set up to feed an inerting gas into an interior of the reactor vessel.

The invention relates to a process for cracking a hydrocarbon-containing feed in a cracking furnace. A plurality of heat exchangers are arranged in the convection zone of the cracking furnace to utilize the heat of flue gas formed in the radiation zone by combustion. Depending on the type and state of matter of the hydrocarbon-containing feed, flow occurs through the heat exchangers to achieve, independently of the type and state of matter of the hydrocarbon-containing feed, an exit temperature of the flue gas in the range from 80&#xb0; C. to 150&#xb0; C.
