    Liquid-solid fluidization studies at room temperature were initiated to evaluate the severity of flow instabilities associated with fluidized beds. In these exploratory tests, bubbling a moderate amount of gas through the fluidized bed completely disrupted the flow pattern. About this book. Introduction. Fluidized beds have gained prominence in many process in­ dustries (including chemicals, petroleum, metallurgy, food and pharmaceuticals) as a means of bringing particulate solids into contact with gases and/or liquids.

    The book starts with a brief history of fluidization from its inception in the ’s. The authors present both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of operating processes that use fluid-bed reactors. Book Description Table of Contents Book Description This reference details particle characterization, dynamics, manufacturing, handling, and processing for the employment of multiphase reactors, as well as procedures in reactor scale-up and design for applications in the chemical, mineral, petroleum, power, cement and pharmaceuticals industries.
