摘要

Process for preparing acroleu00ecna by partial oxidation in the gas phase heterogeneamente catalyzed, and catalyst cancel not supported ".The invention relates to a method for the partial oxidation in the gas phase heterogeneamente catalyzed propylene to produce acrolein with a load of propene catalytic bed 242 120 N1 / 1 sym...H and a total content of Co ~ 2 ~ and saturated hydrocarbons in the reaction product of less than 15% by mol, through which the catalyst is a catalyst in catalytic bed full reverse,Whose active mass is a multimetais oxide in which the molar ratio Co / Fe = 2 to 4, and Co / Mo = 0.3 to 0.7%.
