Book excerpt: Fluid-Solid Reactions, Second Edition takes a detailed and thorough look at the scope of fluid-solid reaction systems, focusing on the four phenomena: external mass transfer, pore diffusion, chemical reaction, and adsorption/desorption. This completely revised new edition builds on the classic original edition through the introduction of cutting-edge new theories and applications, including the formulation and application of a new and convenient law that governs fluid-solid reaction kinetics. This book will be of primary interest to practicing engineers engaged in process research, development, and design in the many fields where fluid-solid reactions are critical to workflow and research. Fluid-solid reactions play a major role in the technology of most industrialized nations. These reactions encompass a very broad field, including the extraction of metals from their ores, the combustion of solid fuels, coal gasification, and the incineration of solid refuse. Features 50% new and revised content, arming researchers with the latest developments in the field Details a new unified approach to modeling the rates of fluid-solid reaction systems Authored by one of the world’s foremost experts on fluid-solid reactions and their applications in the field
