Abstract: Ordered packing, for a reactor for gas phase oxidation of o-xylene and/or naphthalene with molecular oxygen to form phthalic acid anhydride, has flow channels parallel to the long axis of reactor that fills the reactor cross-section to an edge gap whereby the maximum width of the edge gap measured in the plane at right angles to the long axis of the reactor is less than the hydraulic diameter of the flow channels. An ordered packing (1), for a reactor for the gas phase oxidation of o-xylene and/or naphthalene with a molecular oxygen containing gas stream to form phthalic acid anhydride, has flow channels (2) parallel to the long axis of the reactor that fill the reactor cross-section to an edge gap (3) whereby the maximum width of the edge gap (3) measured in the plane at right angles to the long axis of the reactor is less than the hydraulic diameter of the flow channels (2), preferably less than half of the hydraulic diameter of the flow channels (2) and the packing (1) is coated with an oxidation catalyst for phthalic acid anhydride. Independent claims are included for processes for the application or coating of an oxidation catalyst onto the packing (1) by dipping or spraying a suspension containing the catalyst or catalyst precursor onto the packing (1).

Abstract: The invention relates to a vanadium-, phosphorus- and oxygen-containing catalyst that is used for producing maleic anhydride by heterogeneous catalytic gas phase oxidation of a hydrocarbon carrying at least four carbon atoms in which the ratio of phosphorus/vanadium is 0.9 to 1.5. Said catalyst comprises particles with an average diameter of at least 2 mm and the composition has a x-ray powder diffraction pattern, obtained by irradiation with CuK alpha radiation ( lambda = 1.54 10 m), that produces in the 2 theta range of 10 DEG to 70 DEG a signal/noise ratio of

Abstract: Production of maleic anhydride by gas-phase oxidation of C4+ hydrocarbons with oxygen in the presence of a volatile phosphorus compound and a heterogeneous vanadium/phosphorus/oxygen catalyst comprises performing the oxidation in a shell-and-tube reactor comprising at least two sequential cooled reaction zones, in which the first zone is at 350-450 deg C, the second and subsequent zones are at 350-480 and the temperature difference between the hottest and coolest zones is at least 2 deg C. An Independent claim is also included for apparatus for carrying out the process, comprising: a unit for the metered supply of hydrocarbon, oxygen-containing gas and optionally the phosphorus compound; a shell-and-tube reactor comprising at least two sequential cooled reaction zones with independent temperature control; and a unit for separating maleic anhydride and optionally oxygenated hydrocarbon by-products.

Abstract: A catalyst for gas-phase oxidations which comprises an inert support and a catalytically active composition comprising transition metal oxides applied thereto, or a precatalyst, is described. The (pre)catalyst is obtained by treating the inert support with an aqueous suspension or solution of the transition metal oxides or their precursor compounds, where the suspension contains a binder dispersion and the binder is a copolymer of an alpha-olefin and a vinyl-C 2 -C 4 -carboxylate whose vinyl C 2 -C 4 -carboxylate content is at least 62 mol %.

Abstract: Production of phthalic anhydride by gas-phase oxidation of o-xylene or naphthalene in a tubular reactor involves using three or more different catalyst beds with controlled hot-spot temperatures. A method for the production of phthalic anhydride (I) by gas-phase oxidation of xylene and/or naphthalene in a thermostatted tube-bank reactor on 3 or more solid-bed catalysts in 3 different layers involves carrying out the process in such a way that the peak temperature (T2) in the second catalyst layer (in the direction of flow) is up to 50 degrees C below the peak temperature (T1) in the first layer and the peak temperature (T3) in the third layer is 30-100 degrees C below T1.
