Abstract: A method for producing a target compound includes distributing a feed mixture at a temperature in a first temperature range to a plurality of parallel reaction tubes of a shell-and-tube reactor, and subjecting the feed mixture in first tube sections of the reaction tubes to heating to a temperature in a second temperature range and in second tube sections of the reaction tubes arranged downstream of the first tube sections to oxidative catalytic conversion using one or more catalysts. A gas mixture flowing out of the second tube sections is brought into contact in third tube sections arranged downstream of the second tube sections with a catalyst which has a volumetric activity below the highest volumetric activity of the one or the plurality of catalysts arranged in the second tube sections. A gas mixture from the third tube sections is withdrawn from the shell-and-tube reactor without further catalytic conversion.

Abstract: A reactor for carrying out a chemical reaction, which has a reactor vessel and one or more reaction tubes, wherein power input elements for electrical heating of the reaction tube(s) are guided into the reactor vessel. It is provided that the power input elements each have a rod-shaped section that, in each case, runs at a wall passage through a wall of the reactor vessel in such a way that a connection chamber into which the rod-shaped sections project is arranged outside the reactor vessel and adjacently to the wall of the reactor vessel through which the rod-shaped sections run at their wall passages, and that cooling panels through which a cooling fluid can flow are provided in the connection chamber and are arranged between at least two or between at least two groups of the rod-shaped sections that project into the connection chamber.

Abstract: A method of steam cracking using a steam cracking arrangement including an electric cracking furnace without a convection zone and a quench cooling train is proposed, wherein a process gas stream is passed through the cracking furnace and the cooling train. The cooling train is operated to comprise at least two distinct cooling steps arranged in either order, wherein in a first cooling step at least a part of the process gas stream withdrawn from the electric cracking furnace is cooled against vaporizing boiler feed water at an absolute pressure level between 30 and 175 bar and wherein in a second cooling step at least a part of the process gas stream withdrawn from the electric cracking furnace is cooled against a superheated mixture of feed hydrocarbons and process steam used in forming the process gas stream which is thereby heated to a temperature level between 350 and 750° C.

Abstract: A reactor for carrying out a chemical reaction includes a reactor wall and at least one group of M reaction tubes, each of which has an electrically heatable heating section that extends between a first and a second removal region. Each heating section has a respective feed region in a region which extends over 20% to 80% of a heating length of the heating section and electrically conductive feed elements. Each group M is paired with the feed elements connected to the feed regions of the group, and different phases of the alternating current can be fed to different feed elements paired with a group. Each group is paired with M first and M second removal elements connected to the first or second removal regions of the group, respectively. Each group is paired with a first and a second star bridge.

Abstract: A method for producing one or more hydrocarbons, includes subjecting a first feed stream to a steam cracking to obtain a first product stream and subjecting a second feed stream containing ethane to an oxidative dehydrogenation to obtain a second product stream At least a portion of the first product stream is subjected to a treatment to obtain hydrocarbon fractions. The treatment includes a selective hydrogenation of hydrocarbons having two carbon atoms and a demethanization. At least a portion of the second product stream is subjected to a trace removal, which comprises the removal of oxygen and/or acetylene, to obtain an subsequent stream. At least a portion of the subsequent stream is fed to the treatment at a position downstream of the selective hydrogenation and upstream of the demethanization. A portion of the subsequent stream is subjected to a carbon dioxide removal upstream of the feed point into the treatment.

Abstract: A process for producing a target compound includes forming a feed mixture containing at least one reactant compound. The feed mixture is distributed to parallel reaction tubes of one or more shell-and-tube reactors and subjected to oxidative catalytic conversion in the reaction tubes. Steam is added to the feed mixture in an amount such that a steam fraction of the feed mixture is 5 to 95 vol %, oxygen is added to the feed mixture in the form of a fluid containing at least 95 vol % oxygen, and the oxidative catalytic conversion is carried out using one or more catalysts containing the metals molybdenum, vanadium, niobium and optionally tellurium.
