    Abstract: Solution streams are produced from solutions containing partial amounts of starting compounds of elemental constituents of multi-metal oxide composition, and combined to form a total solution stream (S1). S1 is mixed, to form a mixed solution stream (S2). S2 is broken into fine droplets and dried. The solid obtained is calcined at 200-1200[deg]C, to obtain a multi-metal oxide composition. At least two physically separate solutions containing partial amounts of starting compounds of elemental constituents of multi-metal oxide composition in dissolved form are prepared. Solution streams are produced from the obtained solution and combined, to form a total solution stream. The total solution stream is passed through a mixing zone and mixed solution stream comprising the total amount of the required starting compounds in dissolved form is formed. The mix solution stream is broken into fine droplets in the mixing zone or after discharging from the mixing zone. The fine droplets are contacted with hot gas and dried. The solid obtained is treated thermally at elevated temperature to obtain multi-metal oxide composition. The thermal treatment is calcination performed at 200-1200[deg]C. The multi-metal oxide composition has stoichiometry of: Mo1VaM1>bM2>cM3>dM4>eOn. M1>tellurium or antimony; M2>niobium, titanium, tungsten, tantalum, bismuth, zirconium or rhenium; M3>lead, nickel, cobalt, iron, palladium, silver, platinum, copper, gold, gallium, zinc, tin, indium, cerium, iridium, samarium, scandium, yttrium, praseodymium, neodymium or terbium; M4>lithium, sodium, potassium, rubidium, cesium, calcium, strontium or barium; a : 0.01-1; b, c, e : above 0-1; d : above 0-0.5; and n : number determined by the valence and abundance of elements other than oxygen. Independent claims are included for; (1) a multi-metal oxide composition; and (2) A method of heterogeneously catalyzed partial gas phase oxidation and/or ammoxidation of saturated and/or unsaturated hydrocarbon using the multi-metal oxide composition as active composition.

    Abstract: In a process for the two-stage catalytic gas-phase oxidation of propene to acrylic acid, the reaction gas starting mixture is passed, in a tube-bundle reactor, with a propene loading of >=160 l (S.T.P.) of propene/l.h, first over a fixed catalyst bed 1 present in two successive temperature zones A, B and then over a fixed catalyst bed 2 which is housed either in one further temperature zone C or in two further temperature zones D, E, the temperature of the zone A being kept at a lower temperature than the zone B and the temperature of the zone D at a lower temperature than the zone E.
