Features: Fluidization is an emerging discipline in the field of chemical engineering science and technology. Since its inception, it has been widely applied in just half a century. Fluidization generally falls into two major types: disperse fluidization and dense fluidization. Disperse fluidization typically occurs in liquid-solid systems, where good inter-phase contact is achieved, resulting in high heat transfer, mass transfer, and reaction rates. Dense fluidization, on the other hand, generally occurs in gas-solid systems and exhibits characteristics opposite to those of disperse fluidization. Therefore, finding effective methods to transform dense gas-solid fluidization into disperse fluidization has always been a pursuit of Chinese scientists and technologists. The author of this book has systematically summarized and organized more than a decade of research findings, introducing to readers a series of effective methods for achieving disperse fluidization in gas-solid systems. The book provides insights and guidance for improving the operation quality of gas-solid fluidization. The book is divided into seven chapters, covering the prediction and evaluation theories and methods of fluidization quality, inter-particle interactions, fluidization characteristics of ultrafine and sticky particles, particle design, fluid design, internal design, bed design, and external force field methods to improve gas-solid fluidization quality. This book is intended for researchers, engineering technicians, and professionals engaged in chemical reaction engineering, fluidization technology, particle-fluid two-phase flow, and particle research and applications. It can also serve as a teaching reference for teachers and graduate students in relevant disciplines at universities and colleges.
