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 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 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： The invention relates to a method for producing one or more olefins and one or more carboxylic acids, in which one or more paraffins is or are subjected to an oxidative dehydrogenation. For the oxidative dehydrogenation, a reactor (10) having a plurality of reaction zones (11, 12, 13) is used, a gas mixture comprising the one or more paraffins is successively passed through the reaction zones (11, 12, 13), and at least two of the reaction zones (11, 12, 13) are subject to varying temperature influences.

摘要： A process for producing ethylene by oxidative dehydrogenation of ethane using a shell-and-tube reactor having reaction tubes extending between a first end and a second end includes disposing one or more catalyst beds in each of the reaction tubes. In each of the reaction tubes, a ratio of a total length of the one or more catalyst beds between the first end and the second end to a diameter of each of the reaction tubes has a value between 150 and 400. The shell-and-tube reactor is operated at a linear velocity of 250 to 800 cm/s, and the one or more catalyst beds are configured such that a ratio of active catalyst mass to effective cooling area is in a range between 1.5 and 5 kg/m2.

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 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.
