Widely used in adsorption, catalysis and ion exchange, the family of molecular sieves such as zeolites has been greatly extended and many advances have recently been achieved in the field of molecular sieves synthesis and related porous materials. Chemistry of Zeolites and Related Porous Materials focuses on the synthetic and structural chemistry of the major types of molecular sieves. It offers a systematic introduction to and an in-depth discussion of microporous, mesoporous, and macroporous materials and also includes metal-organic frameworks. Provides focused coverage of the key aspects of molecular sieves Features two frontier subjects: molecular engineering and host-guest advanced materials Comprehensively covers both theory and application with particular emphasis on industrial uses This book is essential reading for researches in the chemical and materials industries and research institutions. The book is also indispensable for researches and engineers in R&D (for catalysis) divisions of companies in petroleum refining and the petrochemical and fine chemical industries.

In view of the substantial progress made in the last decade in the fields of zeolites and related materials it was decided to go for an extended 2nd Edition of "Introduction to Zeolite Science and Practice". Unfortunately - as often is the case - this process took more time than expected by the Editors. In the mean time some new texts on zeolites were issued. Nevertheless, the combination of data, discussion and dedication provided by the present book is a unique coverage of the field, in the opinion of the Editors. In the present Edition the number of chapters rose from 16-22. The contributions can be divided into three categories: updated chapters by the original authors, updated chapters by an expanded or new team of authors and completely new chapters. This 2nd Edition also contains new chapters on "Zeolite-based supramolecular assemblies" (by Dirk De Vos and Pierre Jacobs, experts in this area) and on "The use of bulky probe molecules" (by Paul Kunkeler, Roger Downing and one of the Editors). Finally, the super large pore zeolites and the fast growing area of ordered mesoporous materials are dealt with by Eelco Vogt, Charlie Kresge and and Jim Vartuli. The latter two authors belong to the discoverers of the M41S family of mesoporous materials.

This first book to offer a practical overview of zeolites and their commercial applications provides a practical examination of zeolites in three capacities. Edited by a globally recognized and acclaimed leader in the field with contributions from major industry experts, this handbook and ready reference introduces such novel separators as zeolite membranes and mixed matrix membranes. The first part of the book discusses the history and chemistry of zeolites, while the second section focuses on separation processes. The third and final section treats zeolites in the field of catalysis. The three sections are unified by an examination of how the unique properties of zeolites allow them to function in different capacities as an adsorbent, a membrane and as a catalyst, while also discussing their impact within the industry.

This new century will be an age in which humanity will strive for the recovery and preservation of a more natural environment and also for the establishment of clean and safe energy supply technologies. Up until now, environmental pollution and destruction on a global scale as well as the lack of sufficient clean energy have drawn great attention and concern to the vital need for totally new environmentally friendly, ecologically clean chemical technology, materials and processes -- the most important challenge facing chemical scientists for future generations. In this respect, zeolites offer very unique and interesting physicochemical properties such as a pore structure of a molecular scale, ion-exchange capabilities, a strong surface acidity and a unique internal surface topology. It would, therefore, be of great significance to develop well-defined molecular scale catalysts within zeolite cavities and frameworks which would lead to the design of more active and selective photofunctional and photocatalytic systems, particularly systems able to utilise the very abundant solar energy and convert them into safe and useful chemical energy. The central topics of this book is how to utilise photofunctional zeolites for applications in the recovery and preservation of our environment while, at the same time, trying to develop clean and safe energy supply technologies. A vital new era is emerging in the utilisation of the most limitless, clean and efficient energy source -- the sun by applying photofunctional materials. Research on photofunctional zeolites is only the beginning in the harvesting of this vast and powerful energy source not only to develop clean and safe photochemical processes and systems for industry but also to develop systems that can eliminate and cleanse the many devastating toxic agents that are polluting our environment.

This book provides an overview of all new high-silica zeolites which have been discovered between 1975 and 1985. The first part presents some 25 proven recipes for the preparation of high-silica zeolites and describes the characteristics of the materials obtained. This will allow bench-scale production of these materials for scientific research. In the second part, high-silica zeolites with solved structure type are discussed. This part classifies many proprietary materials according to known structure types, and describes the rules and parameters which govern the formation of these materials. In the third part, the formation and characteristics of high-silica zeolites with unknown structure type are discussed. The book contains a wealth of information for all those scientists who incorporate the use of high-silica zeolites in their work.

Cementitious materials are an essential part in any radioactive waste disposal facility. Conditioning processes such as cementation are used to convert waste into a stable solid form that is insoluble and will prevent dispersion to the surrounding environment. It is incredibly important to understand the long-term behavior of these materials. This book summarises approaches and current practices in use of cementitious materials for nuclear waste immobilisation. It gives a unique description of the most important aspects of cements as nuclear waste forms: starting with a description of wastes, analyzing the cementitious systems used for immobilization and describing the technologies used, and ending with analysis of cementitious waste forms and their long term behavior in an envisaged disposal environment. Extensive research has been devoted to study the feasibility of using cement or cement based materials in immobilizing and solidifying different radioactive wastes. However, these research results are scattered. This work provides the reader with both the science and technology of the immobilization process, and the cementitious materials used to immobilize nuclear waste. It summarizes current knowledge in the field, and highlights important areas that need more investigation. The chapters include: Introduction, Portland cement, Alternative cements, Cement characterization and testing, Radioactive waste cementation, Waste cementation technology, Cementitious wasteform durability and performance assessment.

It is difficult to imagine modem technology without small particles, 1-1000 nm in size, because virtually every industry depends in some way on the use of such materials. Catalysts, printing inks, paper, dyes and pigments, many medicinal products, adsorbents, thickening agents, some adhesives, clays, and hundreds of other diverse products are based on or involve small particles in a very fundamental way. In some cases finely divided materials occur naturally or are merely a convenient form for using a material. In most cases small particles play a special role in technology because in effect they constitute a different state of matter because of the basic fact that the surface of a material is different from the interior by virtue of the unsaturated bonding interactions of the outermost layers of atoms at the surface of a solid. Whereas in a macroscale particle these differences are often insignificant, as the 9 surface area per unit mass becomes larger by a factor of as much as 10 , physical and chemical effects such as adsorption become so pronounced as to make the finely divided form of the bulk material into essentially a different material usually one that has no macroscale counterpart.
