Catalysis By Gold


Book Description

Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing gold catalysts and ways to characterise and use them effectively in reactions. The reaction mechanisms and reasons for the high activities are discussed and the applications for gold catalysis considered./a

Design of Thermal Oxidation Systems for Volatile Organic Compounds


Book Description

Controlling the emission of volatile organic compounds (VOC) became a very prominent environmental issue with the passage of the 1990 Clean Air Act Amendments, and will continue to be an environmental priority through the next decade. No single technology has played as important a role in the control of VOC emissions as thermal oxidation. It has the ability to destroy VOCs in a one-step process that produces innocuous by-products. Design of Thermal Oxidation Systems for Volatile Organic Compounds provides all the information needed for developing a thermal oxidation design in a single reference. It covers design, operation, and maintenance as well as the principles behind the classification of volatile organic compounds as hazardous waste. The author explores the primary purpose of thermal oxidizers and discusses their limitations. The book provides: practical, complete, and concise thermal oxidizer design principles an outline of state-of-the-art design principles a practical rather than theoretical approach real industrial examples in each chapter With the new regulations that affect VOC emissions, engineers from such diverse fields as oil refining, chemical distillation and separation processes, and pharmaceutical industries will need to design and implement thermal oxidation systems. Design of Thermal Oxidation Systems for Volatile Organic Compounds provides a reference to the entire design process, from conceptualization to operation and maintenance.




Pillared Clays and Related Catalysts


Book Description

Since the first works introducing the aluminum intercalated clay family in the early 1970s, interest in the synthesis of pillared interlayered clays has increased tremendously, especially research into the properties and applications of new synthesis methods.

Catalytic Application of Nano-Gold Catalysts


Book Description

Gold, considered catalytically inactive for a long time, is now a fascinating partner of modern chemistry, as scientists such as Bond, Teles, Haruta, Hutchings, Ito and Hayashi opened new perspectives for the whole synthetic chemist community. Recently gold has attracted significant attention due to its advantageous characteristics as a catalytic material and since it allows easy functionalization with biologically active molecules. In this context, when gold is prepared as very small particles, it turns out to be a highly active catalyst. However, such a phenomenon completely disappears when the gold particle size grows into the micrometer range. Therefore, the preparation for obtaining an active gold catalyst is so important. The primary objective of this book is to provide a comprehensive overview of gold metal nanoparticles and their application as promising catalysts.
