The book "Studies in Desulfurization of Transportation Fuels" written by B. Suryawanshi provides a comprehensive overview of the various aspects of desulfurization in transportation fuels. With the increasing demand for cleaner fuels, desulfurization has become a crucial step in the fuel processing industry. The book covers topics such as sulfur compounds, their impact on the environment, and the regulations governing their use in fuel quality. The book explores the different desulfurization technologies such as hydrodesulfurization, adsorption, oxidative desulfurization, and deep desulfurization, and their efficiency in removing organic and inorganic sulfur. Catalysts, including zeolites and metal oxides, are also discussed in detail. The book delves into the desulfurization kinetics, sulfur reduction, and selectivity of various desulfurization methods. Furthermore, the book also covers fuel properties and their impact on fuel economy. It delves into sulfur poisoning and its effect on fuel refining. The book examines fuel additives, their effectiveness, and the challenges associated with their use. The book concludes by exploring industrial desulfurization, sulfuric acid production, and sulfur recovery. Overall, this book provides a comprehensive understanding of desulfurization and its impact on transportation fuels. The book is essential reading for researchers, engineers, and professionals in the fuel processing industry, environmental scientists, and policy-makers.
