With propene loading to a fixed bed of 120 Nl / l ยท h or more and a total content of less than 15 mol% of the reaction gas starting mixture of CO 2 and saturated hydrocarbons, propene is converted to acrolein by heterogeneous catalysis. A partial gas phase oxidation method, wherein the catalyst of the catalyst fixed bed is a ring-shaped unsupported catalyst, and the active material of the unsupported catalyst is a molar ratio: Co / Fe = 2 to 4 and Co / Mo A process for producing acrolein by partial gas phase oxidation by heterogeneous catalytic reaction, which is a multimetal oxide such that = 0.3 to 0.7. |
