Title:
アクロレインからアクリル酸への不均一系接触部分気相酸化法
Document Type and Number:
Japanese Patent JP2006523187
Kind Code:
A
Abstract:
The invention relates to a method for the heterogeneously catalysed partial gas phase oxidation of acrolein to form acrylic acid, whereby the initial mixture of reaction gas is oxidised on a fixed-bed catalyst bed which consists of at least two fixed-bed catalyst bed zones and is arranged in two successive temperature zones A and B. The transition from temperature zone A to temperature zone B does not coincide with a transition from a fixed-bed catalyst bed zone to another fixed-bed catalyst bed zone.
