| 摘要 |
<p>The invention relates to the long term operation of a heterogeneously catalysed gas phase partial oxidation of propene in order to form acrolein. The temperature of the solid bed catalyst increases over time, gas phase partial oxidation is interrupted at least once per calendar year, and a gas mixture (G) is guided through the solid bed catalyst having a temperature of between 250 - 550 DEG C, said gas mixture consisting of molecular oxygen, inert gas and, optionally, steam.</p> |
