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 <u>></u> 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. |
