プロペンからアクロレインへの不均一系接触部分気相酸化法
Document Type and Number:
Japanese Patent JP4504355
Kind Code:
B2
Abstract:
In a process for heterogeneously catalyzed partial gas phase oxidation of propene to acrolein, the starting reaction gas mixture is oxidized over a fixed catalyst bed which consists of at least two fixed catalyst bed zones and is accommodated in two successive temperature zones A, B, and the transition from temperature zone A to temperature zone B does not spatially coincide with a transition from one fixed catalyst bed zone to another fixed catalyst bed zone.
