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.

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.

A method for detecting deposits in a pipe system of an apparatus is proposed, the apparatus being flowed through by a fluid. In the method it is provided that at least one microwave probe is introduced into the pipe system in such a way that the fluid flows against a window () of the microwave probe that is transparent to microwave radiation, and that microwaves are coupled into the pipe system by way of at least one microwave probe, wherein a reflection measurement is carried out with one or two microwave probes, and/or at least two microwave probes are introduced into the pipe system at a distance from one another and a transmission measurement is carried out, wherein a comparison of measurement data with a reference or a previous measurement is used to deduce a constriction in the pipe system segment and the free cross-section at the constriction is determined, the detection of a constriction being used to deduce the presence of deposits. Further aspects of the invention relate to a microwave probe for coupling microwave radiation into the pipe system of an apparatus and to a measuring device for carrying out the method that comprises at least one such microwave probe.

The present invention relates to a process for the hydrogenation of substituted or unsubstituted, monocyclic or polycyclicaromatics to form the corresponding cycloaliphatics, in particular of benzene to cyclohexane, by bringing the aromatic into contact with a hydrogen-containing gas in the presence of a catalyst, where hydrogen in which residual gases are present is used.

The invention relates to catalyst packing and a production process for catalyst packing in which a fabricated woven or knitted fabric in the form of continuous web goods is shaped to give a package by stacking a plurality of layers, and segments (S) are cut out of the package and assembled to give one or more course(s) which completely fill the reactor cross section. A reactor containing catalyst packing of this type is particularly suitable for catalytic reactions, preferably for hydrogenations, selective hydrogenations, selective oxidations or isomerizations.
