Abstract: A starting gas stream comprising hydrocarbon is continuously fed to reaction chamber enclosed by shell and having orifice(s) (I) for feeding starting gas stream and orifice(s) (II) for withdrawing product gas stream(s). The starting gas stream is passed through catalyst bed disposed in the chamber and with generation of product gas, and is partially dehydrogenated. The product gas stream is continuously withdrawn from the chamber. The shell surface is manufactured from steel of preset chemical composition. A starting gas stream comprising hydrocarbon to be dehydrogenated is continuously fed to the reaction chamber reaction chamber which is enclosed by a shell which is in contact with the reaction chamber and has orifice(s) (I) for feeding starting gas stream into the reaction chamber and orifice(s) (II) for withdrawing product gas stream(s) from the reaction chamber. The starting gas stream is passed through catalyst bed disposed in the reaction chamber and, with generation of a product gas comprising dehydrogenated hydrocarbon(s), unconverted hydrocarbon to be dehydrogenated and molecular hydrogen and/or steam, and is dehydrogenated partially in an oxidative or non-oxidative manner to dehydrogenated hydrocarbon(s). The product gas stream is continuously withdrawn from the reaction chamber. The surface of the shell in contact with the reaction chamber is manufactured in a layer thickness (d) of 1 mm or more, from a steel (S) which has chromium (in wt.%) (18-30), nickel (9-36), silicon (1-3), nitrogen (0.1-0.3), carbon (0-0.15), manganese (0-4), aluminum (0-4), phosphorus (0-0.05), sulfur (0-0.05), and rare earth metals (0-0.1), and remainder containing iron and impurities. Independent claims are included for the following: (1) shell, which encloses an interior (I) and has orifice (I) for feeding gas stream into interior (I) and orifice (II) for withdrawing a gas stream fed to the interior (I) via orifice (I) from the interior (I). The surface of the shell in contact with the interior (I) is manufactured in a layer thickness (d) of 1 mm or more from steel (S); and (2) use of shell for carrying out heterogeneously catalyzed partial dehydrogenation of hydrocarbon.

Abstract: THE INVENTION RELATES TO A METHOD FOR THE CONTINUOUS HETEROGENEOUSLY CATALYZED PARTIAL DEHYDRATION OF AT LEAST ONE HYDROCARBON TO BE DEHYDRATED IN A REACTOR, SAID REACTOR BEING PRODUCED FROM A COMPOSITE MATERIAL. ON ITS SIDE CONTACTING THE REACTION CHAMBER, THE REACTOR CONSISTS OF A STEEL B HAVING A SPECIFIC ELEMENTAL COMPOSITION, WHICH, ON THE SIDE FACING AWAY FROM THE REACTION CHAMBER, IS PLATED EITHER DIRECTLY OR VIA AN INTERMEDIATE COPPER, OR NICKEL OR COPPER AND NICKEL LAYER ONTO A STEEL A HAVING A SPECIFIC ELEMENTAL COMPOSITION. THE INVENTION ALSO RELATES TO METHODS FOR PARTIAL OXIDATIONS OF THE DEHYDRATED HYDROCARBON AND TO THE REACTOR AS SUCH. STEEL A IS A HIGH-GRADE CHROMIUM-NICKEL STEEL HAVING A LOW Si CONTENT (
