| Title of Invention | PREPARATION OF ACROLEIN OR ACRYLIC ACID OR A MIXTURE THEREOF FROM PROPANE |
|---|---|
| Abstract | Disclosed is a method for producing acrolein, acrylic acid, or a mixture thereof from propane. According to said method, the propane is first dehydrogenated to propene in a heterogeneously catalyzed manner, secondary components are eliminated, the remaining gas mixture containing propane and propene is subjected to heterogeneously catalyzed partial oxidation so as to obtain acrolein, acrylic acid, or a mixture thereof as a target product, target Preparation of acrolein or acrylic acid or a mixture thereof from propane Abstract 5 A process for preparing acrolein or acrylic acid or a mixture thereof from propane, in which the propane is initially dehydrogenated under heterogeneous catalysis to give propene, secondary components are removed and the remaining gas mixture, comprising propane and propene, is subjected to the heterogeneously catalyzed partial oxidation to acrolein or acrylic acid or a mixture thereof as the target product, target 10 product is removed from the product gas mixture and the remaining residual gas, comprising excess oxygen and unconverted propane, is recycled into the propane dehydrogenation in such a way that the other propane fed to the dehydrogenation is at least partly converted under dehydrogenating conditions at the recycle point. |
