Back cover copy

Introduces a simplified description of major catalytic processes including products from the petroleum, chemical, environmental and alternative energy fields Catalysis is central to the chemical industry, as it is directly or involved in the production of almost all useful chemical products. It is central to any technically advanced society from the manufacture of bulk and specialty chemicals, through the production of fuels by petroleum refining to the control of unwanted environmental degradation. Introduction to Catalysis and Industrial Catalytic Processes explains the fundamental principles of catalysis and their applications of catalysis in a simple, introductory textbook that excites those contemplating an industrial career in chemical, petroleum, alternative-energy, and environmental fields in which catalytic processes play a dominant role. The book focuses on non-proprietary, basic chemistries and descriptions of important, currently-used catalysts and catalytic processes. Considerable practical examples, recommendations, and cautions located throughout the book are based on authors’ experience gleaned from teaching, research, commercial development, and consulting, including feedback from many students and associates. The book features: Basic principles of catalysis, including reaction kinetics, simple reactor design concepts, catalyst preparation, characterization, deactivation and regeneration Applications and practice in the industry, including process chemistry, conditions, catalyst design, process design, and catalyst deactivation problems for each catalytic process and regeneration when appropriate Simplified process diagrams providing an overview of principal process units (e.g. reactors and separation units) and important process steps, including reactant and product streams Suggested readings (reviews, books, and journal articles) and Questions are included at the end of each chapter to encourage interested readers to deepen their knowledge of these topics The need for a thorough understanding of fundamental principles of chemistry and catalysis is a given. Introduction to Catalysis and Industrial Catalytic Processes main objective is to transition this knowledge to their commercial applications, especially for the many chemistry and chemical engineering students who spend much of their careers working in industry with catalytic processes.
