Abstract (en)
[origin: WO2007060036A1] A process for preparing acrolein or acrylic acid or a mixture thereof as a target product from propane, in which, in a reaction zone A, propane is partially dehydrogenated under heterogeneous catalysis, molecular hydrogen formed in this way is combusted partly to water and the product gas A thus formed in reaction zone A is used without secondary component removal to charge a reaction zone B in which propylene present in product gas A is partially oxidized to the target product. The target product is removed from the product gas B formed in reaction zone B and the residual gas I which remains, after an aftertreatment thereof comprising a CO2 scrubbing and a partial discharge, is recycled into reaction zone A.
