Method for the production of acrylic acid by means of heterogeneously catalyzed partial gas phase oxidation of propylene |
| abstract |
The invention relates to a method for producing acrylic acid by means of two-stage heterogeneously catalyzed partial gas phase oxidation of propylene. According to said method, previously dehydrogenated propane is used as a propylene source while the first partial oxidation stage is operated so as to limit propylene reaction. Furthermore, unreacted propane and propylene contained in the product gas mixture of the second partial oxidation stage are largely redirected into the propane dehydrogenation process taking place upstream. |
