摘要： A method for producing a target compound, includes distributing feed mixture at a temperature in a first temperature range to a plurality of parallel reaction tubes of a shell-and-tube reactor. The method further includes 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 arranged in the second tube sections. The heating is performed, at least in part, using a catalyst arranged in the first tube sections and having a light-off temperature in the first temperature range.

摘要： 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.

摘要： A method for producing a target compound includes distributing a feed mixture containing ethane to multiple reaction tubes of a shell-and-tube reactor arranged in parallel, and subjecting to an oxidative catalytic conversion of the ethane in the reaction tubes. The catalytic reaction is carried out by means of catalysis zones with different activity arranged in series in the reaction tubes. One or more catalytically active materials and one or more catalytically inactive materials are provided in each of the catalysis zones. The different activity of the catalysis zones is effected by providing the one or more catalytically active materials having identical or essentially identical basic formulation, wherein the one or more catalytically active materials is or are prepared using different calcination intensities.

摘要： 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.

摘要： A method of steam cracking includes using a steam cracking arrangement that has a fired cracking furnace, a quench cooling train, and rotating equipment at least partly driven by electric energy. A process gas stream is passed through the furnace and the cooling train. A steam generation arrangement, operated in thermal association with the cracking arrangement, results in superheated high pressure steam at a first pressure level of 30 and 175 bar absolute pressure and at a first temperature level. No steam at a higher temperature level than the first is generated. The superheated high pressure steam is partially adiabatically and isenthalpically expanded to a second lower pressure level. The first temperature level is selected such that each intermediate temperature level reached at intermediate pressure levels of more than 20 bar during the adiabatic and isenthalpic expansion process is between 5 and 120 K above the dew point of steam.

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.

摘要： A process (100) is proposed for the production of one or more olefins, in which a reaction feed containing oxygen and one or more paraffins is formed and in which a part of the oxygen in the reaction feed is reacted with a part of the one or more paraffins to form the one or more olefins by an oxidative process, to obtain a process gas, the process gas containing at least the unreacted part of the one or more paraffins and oxygen, the one or more olefins, one or more acetylenes, carbon dioxide and water. The process comprises subjecting the process gas or a gas mixture formed using at least a part of the process gas partially or completely to a condensate separation (2), a compression (3), an at least partial removal (4) of the oxygen and acetylene(s) and to one or more stages of a carbon dioxide removal (5) in the order given herein, wherein the at least partial removal (4) of the oxygen and of the acetylene(s) is performed at the same time and by a catalytic conversion using a catalyst comprising copper oxide or ruthenium, and wherein the catalytic conversion is performed at least in part in the form of a hydrogenation. A corresponding plant is also the subject of the present invention.

摘要： Producing a product hydrocarbon includes subjecting a feed mixture containing a feed hydrocarbon and oxygen to selective oxidation to obtain a product mixture containing product hydrocarbon and water. A subsequent mixture is formed from a portion of the product mixture by separating a portion of the water. Oxygen in the feed mixture is partially converted during the selective oxidation, so that the product mixture has a first residual oxygen content and the subsequent mixture has a second residual oxygen content. Detection of the first and/or the second residual oxygen content is performed using a first measuring device. A second measuring device at the end of the catalyst bed detects temperature. Using a process control and/or evaluation unit, measurement data of the first and/or second measuring device(s) are detected and are evaluated and/or processed while obtaining follow-up data. Process control is carried out on the basis of the follow-up data.

摘要： 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.
