Fluidized bed reactor

A fluidized bed reactor is a reactor that uses a gas or liquid to pass a granular solid layer to cause the solid particles to be in a suspended motion state, and to perform a gas solid phase reaction process or a liquid solid phase reaction process. The advantages of the fluidized bed reactor for the gas-solid reaction process fluidized bed reactor are as follows: (1) Because fine powder particles can be used and contact with the fluid in suspension, the fluid-solid phase boundary area is large, which is beneficial to non- The progress of the homogeneous reaction improves the utilization of the catalyst. (2) Due to the intense mixing of the particles in the bed, the temperature and concentration of the particles in the whole bed are uniform, and the heat transfer coefficient between the bed and the inner dip heat exchange surface is very high [200-400 W/(m2•K)] The whole bed has a large heat capacity and high thermal stability, which are beneficial to the isothermal operation of the strong exothermic reaction. This is one of the important reasons for the selection of fluidized beds for the reaction devices of many processes.https://www.syhgzben.com/
