    Abstract: Disclosed is a method for the heterogeneously catalyzed partial gas phase oxidation of propene into acrylic acid, according to which a specifically composed initial reaction gas mixture containing propene and oxygen is oxidized on a first fixed catalyst bed having a constant or increasing volume-specific activity in the direction of flow in a first reaction stage. The resulting gas mixture of the first reaction stage, which contains acrolein, is then oxidized on a second fixed catalyst bed having an increasing volume-specific activity in the direction of flow in a second reaction stage. The molded catalyst bodies of both fixed catalyst beds have an annular shape and are respectively provided with a specific multimetal oxide composition.

    Abstract: A process for the long-term operation of a heterogeneously catalyzed gas phase partial oxidation of acrolein to acrylic acid, in which the temperature of the fixed catalyst bed is increased over time and partial oxidation is interrupted and an oxygen-containing gas is conducted through the fixed catalyst bed before the temperature increase is 8° C.

    Abstract: The invention relates to a method for the heterogeneously-catalysed gas-phase partial oxidation of propene to produce acrolein with a propene loading of the catalyst bed of > 120 Nl/l h and a total content of CO2 and saturated hydrocarbons in the reaction product of less than 15 mol. %, whereby the catalyst in the catalyst bed is an annular full catalyst, the active mass of which is a multi-metal oxide in which the molar ratios are Co/Fe = 2 to 4 and Co/Mo = 0.3 to 0.7.
