The book discusses the sciences of operations, converting raw materials into desired products on an industrial scale by applying chemical transformations and other industrial technologies. Basics of chemical technology combining chemistry, physical transport, unit operations and chemical reactors are thoroughly prepared for an easy understanding.
The book illuminates various aspects of heterogeneous catalysis engineering, from catalysis design, catalyst preparation and characterization, reaction kinetics, mass transfer, and catalytic reactors to the implementation of catalysts in chemical technology. Aimed at graduate students, it is also a useful resource for professionals working in research and development.
The book describes the valorization of biomass-derived compounds over gold catalysts. Since biomass is a rich renewable feedstock for diverse platform molecules, including those currently derived from petroleum, the interest in various transformation routes has become intense. Catalytic conversion of biomass is one of the main approaches to improving the economic viability of biorefineries. In addition, Gold catalysts were found to have outstanding activity and selectivity in many key reactions. This book collects information about transformations of the most promising and important compounds derived from cellulose, hemicelluloses, and woody biomass extractives. Since gold catalysts possess high stability under oxidative conditions, selective oxidation reactions were discussed more thoroughly than other critical reactions such as partial hydrogenation, acetalization, and isomerization. The influence of reaction conditions, the role of the catalyst, and the advantages and disadvantages of using gold are presented for all of the reactions mentioned above. This book provides an overview of the recent research results focusing on application of gold catalysts for synthesis of valuable chemicals using renewable feedstocks.
Biomass has received considerable attention as a sustainable
feedstock that can replace diminishing fossil fuels for the
production of energy and chemicals. At the present moment in the
oil refining, petrochemical and chemical industry, after
fractionation of crude oil, various fractions are upgraded either
to fuels or functionalized to produce intermediates and specialty
chemicals. An analogous concept of biorefining is based on the
utilization of biomass as a renewable source of carbon, which could
be transformed to valuable chemicals. Although various aspects of
biomass transformations are frequently discussed in the literature,
chemical engineering aspects of such transformations are commonly
not considered. The aim of the present book is to fill this
void. * Updates and informs the reader on the latest research findings using original reviews * Written by leading industry experts and scholars * Reviews and analyzes developments in the field
Chemistry and chemical technology have been at the heart of the
revolutionary developments of the 20th century. The chemical
industry has a long history of combining theory (science) and
practice (engineering) to create new and useful products.
Worldwide, the process industry (which includes chemicals,
petrochemicals, petroleum refining, and pharmaceuticals) is a huge,
complex, and interconnected global business with an annual
production value exceeding 4 trillion dollars. Although in industry
special focus is in heterogeneous catalysis, homogeneous,
enzymatic, photochemical and electrochemical catalysis should not
be overlooked; as the major aim is to produce certain chemicals in
the best possible way, applying those types of catalysis, which
suit a particular process in the most optimal way. Catalysis
according to the very definition of it deals with enhancement of
reaction rates, that is, with catalytic kinetics. This book unifies
the main sub disciplines forming the cornerstone of catalytic
kinetics.
Catalytic Kinetics: Chemistry and Engineering, Second Edition offers a unified view that homogeneous, heterogeneous, and enzymatic catalysis form the cornerstone of practical catalysis. The book has an integrated, cross-disciplinary approach to kinetics and transport phenomena in catalysis, but still recognizes the fundamental differences between different types of catalysis. In addition, the book focuses on a quantitative chemical understanding and links the mathematical approach to kinetics with chemistry. A diverse group of catalysts is covered, including catalysis by acids, organometallic complexes, solid inorganic materials, and enzymes, and this fully updated second edition contains a new chapter on the concepts of cascade catalysis. Finally, expanded content in this edition provides more in-depth discussion, including topics such as organocatalysis, enzymatic kinetics, nonlinear dynamics, solvent effects, nanokinetics, and kinetic isotope effects.
