Title:
（メタ）アクリロニトリルの製造方法
Document Type and Number:
Japanese Patent JP7012523
Kind Code:
B2
Abstract:
Provided is a fluidized bed reaction device capable of maintaining reaction performance while stably performing preparation for a long period of time. Fluidized bed reaction device, the fluidized bedreaction device is provided with a fluidized bed reactor, a heat exchanger connected through a reaction gas lead-out pipe of the fluidized bed reactor, and a pipe for introducing powder into the reaction gas lead-out pipe. The reaction gas lead-out pipe is provided with a first part and a second part. The first part extends from the upper part of the fluidized bed reactor along the height direction of the fluidized bed reactor and reaches the highest point of the reaction gas leading-out piping; wherein the second part is connected with the highest point and extends to the heat exchanger, andthe introduction position of the powder is a position in the second part and is lower than the highest point.
