Fine Chemicals through Heterogeneous Catalysis
Nowadays, the chemical industry is under increased pressure to develop cleaner production processes and technologies. Much effort is devoted to the development of heterogeneous catalysts and their application in industrial-scale organic synthesis. This handbook concentrates on current attempts, focusing on fine chemical production. With contributions from an impressive array of international experts, this is essential reading for everyone interested in the advances in this field.
Recent Advances in Zeolite Science
Interest in zeolites continues to grow, making it vital to keep up to date with recent findings. These proceedings include some of the latest discoveries in the zeolite field. Four plenary lectures provide in-depth coverage of key topics, namely the influence of diffusion on catalysis, recent advances in synthesis, modification of zeolites by alumination, and quantum chemical studies of acidity. These are followed by nineteen papers written by contributors from all over the world covering a wide range of material of current interest. Several synthetic studies are presented, including the introduction of heteroatoms to induce higher catalytic acidity. Acidity and catalysis are probed by solid...
Catalysis by Acids and Bases
Because of the great importance of acid catalysis in the petrochemical industry, extensive research has been carried out during the last 30 years concerning the fundamental and applied aspects of catalysis by acids. In contrast, base-catalyzed reactions have received little attention in heterogeneous catalysis. The aim of this symposium was to evaluate our knowledge of the important area of acid and base catalysis and to cover a broad range of solids, zeolite chemistry being only one aspect of heterogeneous catalysis.
Guidelines for Mastering the Properties of Molecular Sieves
Low dimensionality is a multifarious concept which applies to very diversified materials. Thus, examples of low-dimensional systems are structures with one or several layers, single lines or patterns of lines, and small clusters isolated or dispersed in solid systems. Such low dimensional features can be produced in a wide variety of materials systems with a broad spectrum of scientific and practical interests. These features, in turn, induce specific properties and, particularly, specific transport properties. In the case of zeolites, low dimensionality appears in the network of small-diameter pores of molecular size, extending in one, two or three di mensions, that these solids exhibit as ...
Zeolites: Facts, Figures, Future
This two-volume work contains over 140 papers which, together, reflect the current status of zeolite science and technology encompassing high and low silica zeolites, pillared clays, molecular sieves, microporous metallosilicates, crystalline silica polymorphs, crystalline microporous aluminophosphates and their isomorphically substituted forms. The five plenary invited lectures summarize current knowledge and address a number of topical areas such as the enumeration of theoretically possible frameworks, the use of sophisticated physical methods to unravel and characterise new molecular sieve materials, the potential of molecular sieves as catalysts for chemical intermediate and commodity synthesis and conversion, the role of zeolites in fluid catalytic cracking, and new zeolitic materials. Specific aspects of zeolite science are highlighted in the ten keynote lectures of which three are on synthesis and modification, one on new materials, one on characterization, two on structure and theory, one on metals in zeolites, and two on catalytic topics. All the contributions in this book reflect the high quality of research being carried out throughout the zeolite community.
Zeolites: A Refined Tool for Designing Catalytic Sites
Formerly, the catalytic use of zeolites was exclusive to the field of acid catalysis. Nowadays, zeolites also find applications as catalysts in a wide array of chemical reactions such as; base catalyzed reactions, Redox reactions and catalytic reactions on transition metals and their complexes in confined environments. The concepts of Brønsted or Lewis acid-base pairs are adequately illustrated in the literature and well-understood in terms of structural and electronic properties of zeolites. By contrast, properties of chemically modified silicates, aluminosilicates and aluminophosphates have not yet been fully explored. The list of oxydo-reduction reactions performed in the presence of the...
Nanostructured Catalysts
With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide ...
Zeolites and Mesoporous Materials at the Dawn of the 21st Century
The Zeolites and Mesporous Materials at the Dawn of the 21st Century Proceedings are the expression of the oral and poster communications which where presented during the 13th International Zeolite Conference (IZC). They are subdivided into 32 thematic sessions starting from the genesis of materials to their applications through their characterisation. The paper volume contains the full texts of the 5 plenary and 6 keynote lectures and informative summaries of 150 oral and 540 poster presentations. These contributions have been selected among the 903 submissions received from a total of 57 countries! In order to gather all the communications in a handy document, the full texts of oral and po...
Impact of Zeolites and other Porous Materials on the New Technologies at the Beginning of the New Millennium
Crystalline solids with highly structured micro-scale pores are called zeolites. Their well-defined structure and large contact surface make them extremely useful as catalysts. Their most common use is in washing powders. Different features are caused by the shape and size of the pores and the presence of different metals in the crystal structure. Research is conducted both towards better understanding of the relations between form and function and towards identifying new possible uses. This title presents a collection of contributions from internationally renowned researchers in the field of the Science and Technology of micro and mesoporous materials. The aim of the conference is to create an international forum where researchers from academia as well as from industry can discuss ideas and evaluate the impact of zeolites, and other porous materials, on new technologies at the beginning of the new millennium. · Gives the most recent developments in the origin, synthesis and characterisation of zeolitic materials · Outlines the impact and application of zeolites in various industrial processes · An adjourned state of art in the field of zeolites and other porous materials
Handbook of MTBE and Other Gasoline Oxygenates
This handbook presents the outlook for future production and consumption of MTBE and other oxygenates worldwide and studies new catalytic systems and modern methods for the synthesis and commercial production of methyl tertiary-butyl ether (MTBE) and related ethers. The scope of this sophisticated guide extends from process chemistry fundamentals and reaction kinetics to environmental remediation technologies and industry responses to conflicting calls for MTBE phase-out and higher-octane products. Well-illustrated with over 200 figures and tables, this authoritative Handbook details bioremediation, air stripping, and oxidation and adsorption processes for MTBE removal.
