This book provides a review of worldwide developments in ammonia synthesis catalysts over the last 30 years. It focuses on the new generation of Fe1-xO based catalysts and ruthenium catalysts — both are major breakthroughs for fused iron catalysts. The basic theory for ammonia synthesis is systematically explained, covering topics such as the chemical components, crystal structure, preparation, reduction, performance evaluation, characterization of the catalysts, the mechanism and kinetics of ammonia synthesis reaction. Both theory and practice are combined in this presentation, with emphasis on the research methods, application and exploitation of catalysts. The comprehensive volume includes an assessment of the economic and engineering aspects of ammonia plants based on the performance of catalysts. Recent developments in photo-catalysis, electro-catalysis, biocatalysis and new uses of ammonia are also introduced in this book. The author, Professor Huazhang Liu, has been engaged in research and practice for more than 50 years in this field and was the inventor of the first Fe1-xO based catalysts in the world. He has done a lot of research on Fe3O4 based- and ruthenium based-catalysts, and has published more than 300 papers and obtained 21 patents during his career.

This book follows the 2002 edition of Catalysis by Ceria and Related Materials, which was the first book entirely devoted to ceria and its catalytic properties. In the ten years since the first edition a massive amount of work has been carried out in the field, and ceria has gained a prominent position in catalysis as one of the most valuable material for several applications.

The demand for hydroprocessing catalysts has shown an increasing trend, because of their applications in refining of petroleum and biofuels, in order to comply with strict environmental regulations controlling emissions from transportation vehicles. Transport fuel is dominated by fossil fuels with carbon emission intensive production methods. If we are to move away from these sources, the alternative is to produce liquid fuels from agricultural stocks -- crops, crop waste, forestry waste or algae. Converting these feedstocks into high quality fuels is a considerable challenge. By describing the current status in processing agricultural feedstock into high quality liquid transport fuels, the authors set out the means to develop better chemistry and catalysis for the necessary conversion processes. This book offers an intriguing insight into the mechanisms and protocols involved in new hydroprocessing catalysts and processes, and covers the methods for upgrading these liquids to modern transport vehicles suitable for operation in modern gasoline and diesel engines. It provides an introduction to the mechanism of hydroprocessing reactions, application of different metals in hydroprocessing, the effect of catalyst supports, applications in refining new feedstock, renewable fuels standards, the management of spent hydroprocessing catalysts, and hydrogen production. Hydroprocessing Catalysts and Processes will prove useful for both researchers in academe and industry concerned with future fuels development and treatment to produce current and future liquid transport fuels. Contents: Preface Hydroprocessing and the Chemistry Stabilization of Bio-Oil to Enable Its Hydrotreating to Produce Bio-Fuels Hydroprocessing Catalysts: Inexpensive Ni Based Non-Sulfided Catalysts Catalytic Upgrading of Pinewood Pyrolysis Bio-Oil Over Carbon-Encapsulated Bimetallic Co-Mo Carbides and Sulfides Catalysts Hydroprocessing Catalysts for Algal Biofuels Effects of Catalyst Support on Hydroprocessing Commercial Hydroprocessing Processes for Bio-Feedstock Renewable Fuels and Fuel Regulations and Standards Spent Hydroprocessing Catalysts Management Hydrogen Production Readership: Graduate students in catalysis, refinery feedstock operations and planners, fuel technologists.

The UK Catalysis Hub is a consortium of universities working together on fundamental and applied research to find out how catalysts work and to improve their effectiveness. The contribution of catalysis to manufacturing contributes to almost 40% of global GDP, making development and innovation within the field integral to industry. Modern Developments in Catalysis provides a review of current research and practise on catalysis, focussing on five main themes: catalysis design, environmental catalysis, catalysis and energy, chemical transformation and biocatalysis and biotransformations. Topics range from complex reactions to the intricacies of catalyst preparation for supported nanoparticles, while chapters illustrate the challenges facing catalytic science and the directions in which the field is developing. Editor leaders of the UK Hub, this book provides insight into one of the most important areas of modern chemistry — it represents a unique learning opportunity for students and professionals studying and working towards speeding-up, improving and increasing the rate of catalytic reactions in science and industry.

The Industrial and Engineering Chemistry Division (I&EC) of the American Chemical Society celebrated the centennial of its establishment in 2008. I&EC was the first technical division established within ACS, and as part of the commemorations planned this book has been produced. The theme of the book is innovation and creativity in the chemical industry, where industrial chemists and chemical engineers have made and will make major contributions. This book provides broad coverage of several significant innovations in chemistry that have led, or will lead, to global industrial developments. The material emphasizes how basic science discoveries have been translated into practice. The book will give readers insight into the nature of developing industries from laboratory discoveries. Innovations in industrial and Engineering Chemistry not only chronicles the creativity of our industry, but also reveals the nature of discovery and innovation. There are chapters that are retrospective in nature as well as chapters that are more prospective (for example, green chemistry). The book is not just a history or commemorative, but a compendium of the nature of innovation in our field. The book covers traditional chemical and petrochemical industries, but also emerging fields ionic liquids. The book is a true resource for professionals.

to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitively expensive. There are few chemical-or oil-based material items in modem society that do not depend in some way on a catalytic stage in their manufacture. Apart from manu facturing processes, catalysis is finding other important and ever-increasing uses; for example, successful applications of catalysis in the control of pollution and its use in environmental control are certain to increase in the future. The commercial importance of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists, including chemists, physicists, chemical engineers, and material scientists. Increas ing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recently as sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 1950s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth. In view of this situation, we felt there was a need for a collection of monographs, each one of which would deal at an advanced level with a selected topic, so as to build a catalysis reference library.
