Book Description
Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it’s based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.

Book Description
Goro nickel oxide particles with size range between 300mum and 600mum were reduced with hydrogen gas in the temperature range between 400°C and 1000°C. The rate of reduction increased with increasing temperature between 400°C and 600°C, but gradually decreased between 600°C and 900°C. It then increased dramatically between 950°C and 1000°C. Thermo-gravimetric analysis and shrinking core model were applied to analyze the kinetics of the gas-solid reaction in this case. The investigation found that between 400°C and 600°C, the rate of reduction is controlled by the chemical reaction. Above 600°C, the rate controlling mechanism became a mixed model consisting of chemical reaction control and gas diffusion in solid product control. The influence of the latter became stronger as the temperature increased. Structural changes were also observed in reduced nickel at this stage and linked to the rate controlling mechanism.
