    Abstract: A method for filling a reactor with catalyst particles (I) containing an active multi-element oxide material (II) (at least on the surface), involves using catalyst particles containing a substance (III) which is liquid at 20[deg]C and 1 atm. Independent claims are also included for (1) a reactor filled with (I); and (2) a method for the production of acrylic acid by the catalytic gas-phase oxidation of acrolein in such a reactor.

    Abstract: Continuous heterogeneously catalyzed partial dehydrogenation of at least one hydrocarbon to be dehydrogenated in the gas phase involves at least one catalyst bed disposed in the reaction chamber and with generation of a product gas comprising the at least one dehydrogenated hydrocarbon, unconverted hydrocarbon to be dehydrogenated and molecular hydrogen and/or steam, is dehydrogenated partially in an oxidative or non-oxidative manner to at least one dehydrogenated hydrocarbon, and at least one product gas stream is withdrawn continuously from the reaction chamber. Process for continuous heterogeneously catalyzed partial dehydrogenation of at least one hydrocarbon to be dehydrogenated in the gas phase involves a reaction chamber enclosed by a shell which is in contact with the reaction chamber and has at least one first orifice for feeding at least one starting gas stream into the reaction chamber and at least one second orifice for withdrawing at least one product gas stream from the reaction chamber, at least one starting gas stream comprising at least one hydrocarbon to be dehydrogenated is fed continuously in the reaction chamber. The at least one hydrocarbon to be dehydrogenated is conducted through at least one catalyst bed disposed in the reaction chamber and with generation of a product gas comprising the at least one dehydrogenated hydrocarbon, unconverted hydrocarbon to be dehydrogenated and molecular hydrogen and/or steam, is dehydrogenated partially in an oxidative or non-oxidative manner to at least one dehydrogenated hydrocarbon, and at least one product gas stream is withdrawn continuously from the reaction chamber. The shell is manufactured from a composite material which, on its side B in contact with the reaction chamber, consists of steel B comprising (wt.%): chromium (18-30), nickel (9-37), silicon (1-4), aluminum (>=0-4), nitrogen (>=0-0.3), carbon (>=0-0.15), manganese (>=0-4), phosphorus (>=0-0.05), sulfur (>=0-0.05), and at least one rare earth metal (>=0-0.1), and iron and impurities resulting from production. The steel B, on its side A facing away from the reaction chamber, is plated either directly or via an intermediate layer of copper, and/or nickel, onto steel A comprising (wt.%): chromium (15-20), nickel (6-18), silicon (>=0-0.8), aluminum (>=0-0.8), nitrogen (>=0-0.3), carbon (>=0-0.15), molybdenum (>=0-4), manganese (>=0-2), titanium (>=0-0.8), niobium (>=0-1.2), vanadium (>=0-0.9), boron (>=0-0.1), phosphorus (>=0-0.05), sulfur (>=0-0.05), iron and impurities resulting from production, or a composition comprising (wt.%) Cr (19-23), Ni (30-35), Co (>=0-1), Si (>=0-1), Al (0.15-0.7), C (>=0-0.12), Mn (>=0-2), Cu (>=0-0.75), Ti (0.15-0.7), Nb (>=0-0.1), P (>=0-0.05), S (>=0-0.05) and iron and impurities resulting from production. An independent claim is included for a shell encloses an interior and has at least one first orifice for feeding at least one gas stream into the interior and at least one second orifice for withdrawing a gas stream fed to the interior beforehand via the at least one first orifice O1 from the interior. The shell is manufactured from a composite material which, on its side B in contact with the reaction chamber, consists of steel B on its side A facing away from the reaction chamber is plated either directly or via an intermediate layer of copper and/or nickel onto steel A.

    Abstract: The invention relates to a long-life method for two-stage heterogeneously-catalysed gas phase partial oxidation of propene into acrylic acid. According to said method, the temperature of the fixed catalyst beds is increased overtime; the gas phase partial oxidation is interrupted from time to time and, when the temperature of said fixed catalyst beds is increased, a gas mixture, containing oxygen, is led through the fixed catalyst beds.
