Development and applications of liquid-solid circulating fluidized beds—Process integration and intensification

Liquid-solid circulating fluidized beds (LSCFBs) have been developing for the past 30 years as a new type of fluidized bed reactor. It possesses many advantages, such as high mass and heat transfer efficiency, large operating intensity, small footprint, combining two independent reactions, etc., and has a broad application prospect in the integration and intensification of traditional chemical processes. In this paper, the development history, equipment structure and basic characteristics of LSCFBs were introduced. It mainly focuses on how to achieve the process integration and intensification of LSCFBs in the following applications: protein extraction, lactic acid fermentation and separation process, phenol removal from phenol-containing wastewater and biological treatment of wastewater. Finally, the future development of LSCFBs was prospected. It was proposed that in the future industrial production process, the reactor can be effectively integrated and improved according to the needs of the process and the properties of the reactor. Based on the integration and intensification of the reaction process, new ideas can be provided for future revolution in production patterns.
