Abstract: In the production of (meth)acrylic acid ((M)AA) by passing a gaseous mixture of saturated hydrocarbon precursor(s) (SHP's), oxygen and inert gas through a reactor charged with a mixed metal oxide catalyst (M) containing molybdenum and vanadium, (M) is contained in two beds (I) and (II) of different composition, spaced in the flow direction, having specific selectivity properties on increasing the temperature. Production of (meth)acrylic acid ((M)AA) by heterogeneous gas-phase oxidation at elevated temperature involves passing a gaseous mixture of saturated hydrocarbon precursor(s) (SHP's), oxygen and inert gas(es) at initial pressure P through a reactor charged with a catalyst comprising (as active mass) a mixed metal oxide (M) containing molybdenum and vanadium, at least one of tellurium, antimony and bismuth and at least one of niobium, tantalum, tungsten, cerium and titanium and having an X-ray diffractogram peaks at 2tau values of 22.2 +- 0.5[deg] (h) (strongest peak; half-value breadth at most 0.5[deg]), 27.3 +- 0.5[deg] (i) (half-value breadth 1.0[deg] or less) and 28.2 +- 0.5[deg] (k) (half-value breadth 1.0[deg] or less). The novel feature is that the whole of (M) is contained in two beds (I) and (II) of different composition, spaced in the flow direction. Beds (I) and (II) are such that if the particular bed was the only catalyst present in the same reactor the respective selectivities S1> and S2> for (M)AA would have maximum values (on increasing the conversion of SHP's by increasing the temperature under otherwise identical conditions on a single pass of gas through the reactor) of S1>max and S2>max respectively, where S1>max occurs at lower SHP conversion than S2>max and at an increasing SHP conversion S1> is less than S2>, whereas S1>max is more than S2>max.

Abstract: In a process for the preparation of acrolein or acrylic acid or a mixture thereof from propane, the propane is subjected, in a first reaction stage, to a partial dehydrogenation under heterogeneous catalysis to give propene, of the components contained in the product gas mixture formed in the first reaction stage other than propene and propane at least a portion of the molecular hydrogen present is then separated off from said mixture and the product gas mixture is then used for the preparation of acrolein and/or acrylic acid by gas-phase catalytic propylene oxidation, molecular nitrogen being present for diluting the reaction gas mixture during the propylene oxidation.

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.

Abstract: The invention relates to a method for producing shell catalysts for the catalytic vapor-phase oxidation of aromatic carboxylic acids and/or carboxylic acid anhydrides comprised of a supporting core and of catalytically active metal oxides which are deposited in a shell-shaped manner on said supporting core. The inventive catalysts are obtained by spraying an aqueous active mass suspension, said suspension containing the active metal oxides, at higher temperatures onto the hot supporting material which has a temperature ranging from 50 to 450° C. The aqueous active mass suspension contains 1 to 10 wt. %, with regard to the solid content of the active mass suspension, a binding agent comprised of A) a polymerizate obtained by radical polymerization, containing 5 to 100 wt. % of monomers (a) in the form of ethylenically unsaturated acid anhydrides or ethylenically unsaturated dicarboxylic acids whose carboxyl groups can form an anhydride and containing 0 to 95 wt. % monoethylenically unsaturated monomers (b) with the provision that the monomers (a) and (b) comprise, on average, a maximum of 6 carbon atoms which are not functionalized with groups containing oxygen, and of B) an alkanolamine having at least 2 OH groups, a maximum of 2 nitrogen atoms and a maximum of 8 C-atoms, whereby the weight ratio A:B ranges from 1:0.05 to 1:1.
