Title:
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 JP4520980
Kind Code:
B2
Abstract:
The invention relates to a method for the heterogeneously catalysed partial gas phase oxidation of propene to form acrolein, whereby the initial mixture of reaction gas is oxidised on a fixed-bed catalyst bed arranged in two successive reaction zones A and B, with a propene load < 160 NI propene/I fixed-bed catalyst bed.h. The highest temperature of the reaction gas mixture inside the reaction zone A is higher than the temperature of the reaction gas mixture inside the reaction zone B.
