Micro Fluidization: Fundamentals and Applications

By Dingrong Bai, Guangwen Xu, Mingyang Liu, et al.

In this first-ever monograph on micro fluidized beds, the authors will systematically and comprehensively summarize the characteristics of the technology. The book is prepared in three parts. In the first part, we will provide a short description of the background and history of the micro fluidized bed research and development. Then, we will devote to summarizing and analyzing the hydrodynamic characteristics of gas-solid micro fluidized beds. We will present detailed research results of delayed onsets of minimum, bubbling, and slugging fluidization regimes, as well as of the advanced transitions to turbulent and fast fluidization regimes. Based on these results, the wall effects - the key mechanism resulting in the unique behavior of micro fluidization - are comprehensively analyzed. Following, we discuss gas and solids mixing characteristics in terms of gas residence time distribution, gas backmixing, and solids mixing. We show that the major characteristic of micro fluidized bed is the near-plug flow of fluid in the bed. This character defines the distinctions between micro fluidized beds and macro fluidized beds. Furthermore, fluidization regime maps are developed to define fluidization regimes and their transitions in micro fluidized beds.

In the second part of the book, we focus on presentations of the so-called micro fluidized bed reaction analyzer (MFBRA) - a powerful tool for catalyst screening, process development, optimization of reaction parameters, studies of reaction mechanism and kinetics, among many other purposes. We describe in detail the MFBRA's system design characteristics, analytic methodologies, and various applications in thermochemical and catalytic reaction analysis. We will also present examples to show how the MFBRA helped the development, design, and commercialization of several industrial processes.

In the third part of the book, we present recent investigations of liquid-solid, and gas-liquid-solid micro fluidization systems. Hydrodynamics, mass transfer, and wide applications of these micro fluidized beds are discussed. Lastly, we will present future prospects for the development, research, and application of micro fluidized beds.
