    • The present invention provides a process of producing unsaturated acids from unsaturated aldehydes by fixed-bed catalytic partial oxidation in a shell-and-tube heat exchanger-type reactor, as well as a shell-and-tube heat exchanger-type reactor for use in the process. In the invention, second-stage reaction zone of mainly producing unsaturated acids by the catalytic vapor phase oxidation of an unsaturated aldehyde-containing gas mixture produced in a first-stage reaction zone with molecular oxygen is divided into two or more shell spaces by at least one partition. Each of the divided shell spaces is filled with a heat transfer medium, and the heat transfer medium in each shell space is maintained at isothermal temperature or a temperature difference of 0-5 °C. Also, in order to protect catalyst layers from a highly exothermic reaction, the process is performed at a limited temperature difference between the temperature at a hot spot and the temperature of the heat transfer medium. Also, in order to facilitate the removal of heat generation at a location where the partition is placed, a reaction inhibition layer is disposed in that location. The improved heat control system for reactors provided according to the present invention can secure the heat stability of the catalyst layer, reduce the amount of byproducts, and increase the yield of a final product.
    • 本发明提供了一种在壳管式热交换器型反应器中通过固定床催化部分氧化由不饱和醛生成不饱和酸的方法,以及用于在管式热交换器型反应器中使用的管壳式热交换器型反应器 的过程。 在本发明中,通过在分子氧的第一阶段反应区中产生的不饱和醛的气体混合物的催化气相氧化主要生成不饱和酸的第二阶段反应区至少分成两个或更多个壳层空间 一个分区。 每个分开的壳体空间填充有传热介质,并且每个壳体空间中的传热介质保持在等温温度或0-5℃的温差。 此外,为了保护催化剂层免受高放热反应,该过程在热点温度与传热介质的温度之间的有限温度差下进行。 此外,为了便于在隔离物的位置除去发热,在该位置设置反应抑制层。 根据本发明提供的用于反应器的改进的热控制系统可以确保催化剂层的热稳定性,减少副产物的量,并提高最终产品的产率。
