| zeolite molecular sieves structure chemistry and use: Molecular Sieves Rosemarie Szostak, 2013-06-29 From areport by a Lieutenant Colonel W.A. Ross (Chern. News, Nov.15, 1878, p. 236). Progress did not accelerate during the next 50 years. McBain, in his clas sic 1932 book, The Sorption oi Gases by So lids, devoted a chapter to sorp tion by chabasite, other zeolites, and permeable crystals. McBain remarked that great interest attaches to the finding of Weigel and Steinhoff [0. Weigel and E. Steinhoff, Z. Kris!., 61, 125 (1925{raquo}) that chabasite rapidly sorbs the vapors of water, methyl and ethyl alcohol and formie acid, whereas acetone, ether and benzene are largely excluded. The significance of their results was pointed out by McBain [J.W. McBain, Colloid. Syrnp. Mon., 20, 1 (1926{raquo}) and recognized by alliater writers. It is evident that the partially dehydrated chabasite forms a nearly perfect molecular sieve or a semipermeable membrane of extremely regular structure ... . While the significance of the above observation may have been recog nized, it had little impact. Thus, an eminent pioneer in the synthesis and characterization af zeolites, Professor R.M. Barrer, spent nearly two dec ades (following his Ph. D. studies in the 1930s) developing a firm foundation for the rapid growth in scientific understanding and industrial applications of zeolites which has taken place during the last 30 years. |
| zeolite molecular sieves structure chemistry and use: Nanochemistry Geoffrey A. Ozin, André C. Arsenault, Ludovico Cademartiri, 2009 The global success of the 1st edition of Nanochemistry, along with exceptionally rapid change in the field, has necessitated the publication of a 2nd edition after only three years. This truly major update highlights the latest breakthroughs using more than eighty new case histories, more problem sets, and more teaching principles. Nanotechnology is touted to begin a new era by bringing us materials that were not available before. This book describes the fascinating chemistry behind nanotechnology in a clear and easy to read style. Aimed at teachers, graduate students and advanced undergraduates it provides an authoritative, rigorous and hype-free guide to this burgeoning field. For those who already have some knowledge of the subject, the book remains invaluable as a reference and source of inspiration for future research or teaching. With a combined total of over forty years teaching and research experience, the authors are leaders in the fields of materials chemistry and nanochemistry. They have chosen to focus on concepts rather than formulas whilst describing all the techniques commonly used to synthesize nanomaterials. Problem sets are used to get students to thinking creatively and laterally about what they have learnt. The questions are designed to draw connections between subjects, fields and topics - of fundamental importance for anyone intending to work in such an interdisciplinary field. Nanochemistry is long but later chapters do not require knowledge of earlier sections so it can be read a little at a time. Reviews of the first edition stated that it is one of the most entertaining books in science, given the many figures, the variety of subjects and the well thought out structure. Suitable for those coming from a physics, biology, medicine, materials science, engineering or chemistry background, the book is ideal for whoever needs a birds-eye view of the field. The extensive bibliography allows the reader to find any level of detail behind each of the subjects. Nowhere else in the literature is it possible to find such a comprehensive and up-to-date look at the chemistry of nanotechnology. |

| zeolite molecular sieves structure chemistry and use: Zeolite Microporous Solids: Synthesis, Structure, and Reactivity E.G. Derouane, Francisco Lemos, Claude Naccache, Fernando Ramôa Ribeiro, 2012-12-06 Intensive research on zeolites, during the past thirty years, has resulted in a deep understanding of their chemistry and in a true zeolite science, including synthesis, structure, chemical and physical properties, and catalysis. These studies are the basis for the development and growth of several industrial processes applying zeolites for selective sorption, separation, and catalysis. In 1983, a NATO Advanced Study Institute was organized in Alcabideche (portugal) to establish the State-of-the-Art in Zeolite Science and Technology and to contribute to a better understanding of the structural properties of zeolites, the configurational constraints they may exert, and their effects in adsorption, diffusion, and catalysis. Since then, zeolite science has witnessed an almost exponential growth in published papers and patents, dealing with both fundamentals issues and original applications. The proposal of new procedures for zeolite synthesis, the development of novel and sophisticated physical techniques for zeolite characterization, the discovery of new zeolitic and related microporous materials, progresses in quantum chemistry and molecular modeling of zeolites, and the application of zeolites as catalysts for organic reactions have prompted increasing interest among the scientific community. An important and harmonious interaction between various domains of Physics, Chemistry, and Engineering resulted therefrom. |
| zeolite molecular sieves structure chemistry and use: Sintering and Catalysis G. Kuczynski, 2012-12-06 The proceedings of the 4th International Conference on Sin tering and Related Phenomena, contained in this volume, have been broadened in scope to include the phenomena of sintering and coa lescence of catalytic materials dispersed upon refractory oxides. For it has long been recognized within the circles of chemists and chemical engineers working in the field of catalysis that one of the chief causes of the decline in heterogeneous catalytic activity and/or selectivity is, indeed sintering, or perhaps using a better term, coalescence of the supported catalytic metal and compounds thereof. Essentially catalytic deactivation by sintering is now weIl recognized as Ostwald ripening; which of course is a phenome non familiar to scientists grappling with the problem of sintering of powder compacts. The 4th Conference at Notre Dame marks the first occasion at which scientists and engineers of each discipline were assembled in the same room to exchange views on these phenome na of mutual concern. In the wake of the Conference at Notre Dame, all parties acknowledged the synergistic benefit which issued from this exchange, both at the formal and informal level. All were persuaded that signal benefits will be realized by a continuation of this collab oration in the form of future sintering conferences in which both powder metallurgists and catalytic scientists and engineers would participate. |
| zeolite molecular sieves structure chemistry and use: Introduction to Zeolite Science and Practice P.A. Jacobs, E.M. Flanigen, J.C. Jansen, Herman van Bekkum, 2001-06-26 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. |

| zeolite molecular sieves structure chemistry and use: Structure and Reactivity of Metals in Zeolite Materials Joaquin Peréz-Pariente, Manuel Sánchez-Sánchez, 2018 This volume provides the reader with the most up-to-date and relevant knowledge on the reactivity of metals located in zeolite materials, either in framework or extra-framework positions, and the way it is connected with the nature of the chemical environment provided by the host. Since the first report of the isomorphous substitution of titanium in the framework of zeolites giving rise to materials with unusual catalytic properties, the incorporation of many other metals have been investigated with the aim for developing catalysts with improved performance in different reactions. The continuous expansion of the field, both in the variety of metals and zeolite structures, has been accompanied by an increasing focus on the relationship between the reactivity of metal centers and their unique chemical environment. The concepts covered in this volume are of interest to people working in the field of inorganic and physical chemistry, catalysis and chemical engineering, but also for those more interested in theoretical approaches to chemical reactivity. In particular the volume is useful to postgraduate students conducting research in the design, synthesis and catalytic performance of metal-containing zeolites in both academic and application contexts. |

| zeolite molecular sieves structure chemistry and use: Deactivation And Regeneration Of Zeolite Catalysts Michel Guisnet, Fernando Ramoa Ribeiro, 2011-02-21 In chemical processes, the progressive deactivation of solid catalysts is a major economic concern and mastering their stability has become as essential as controlling their activity and selectivity. For these reasons, there is a strong motivation to understand the mechanisms leading to any loss in activity and/or selectivity and to find out the efficient preventive measures and regenerative solutions that open the way towards cheaper and cleaner processes. This book covers the fundamental and applied aspects of solid catalyst deactivation in a comprehensive way and encompasses the state of the art in the field of reactions catalyzed by zeolites. This particular choice is justified by the widespread use of molecular sieves in refining, petrochemicals and organic chemicals synthesis processes, by the large variety in the nature of their active sites (acid, base, acid-base, redox, bifunctional) and especially by their peculiar features, in terms of crystallinity, structural order and textural properties, which make them ideal models for heterogeneous catalysis. The aim of this book is to be a critical review in the field of zeolite deactivation and regeneration by collecting contributions from experts in the field which describe the factors, explain the techniques to study the causes and suggest methods to prevent (or limit) catalyst deactivation. At the same time, a selection of commercial processes and exemplar cases provides the reader with theoretical insights and practical hints on the deactivation mechanisms and draws attention to the key role played by the loss of activity on process design and industrial practice./a |

| zeolite molecular sieves structure chemistry and use: Catalysis and Zeolites Jens Weitkamp, Lothar Puppe, 2013-04-17 Zeolites occur in nature and have been known for almost 250 years as alumino silicate minerals. Examples are clinoptilolite, mordenite, offretite, ferrierite, erionite and chabazite. Today, most of these and many other zeolites are of great interest in heterogeneous catalysis, yet their naturally occurring forms are of limited value as catalysts because nature has not optimized their properties for catalytic applications and the naturally occurring zeolites almost always contain undesired impurity phases. It was only with the advent of synthetic zeolites in the period from about 1948 to 1959 (thanks to the pioneering work of R. M. Barrer and R. M. Milton) that this class of porous materials began to playa role in catalysis. A landmark event was the introduction of synthetic faujasites (zeolite X at first, zeolite Y slightly later) as catalysts in fluid catalytic cracking (FCC) of heavy petroleum distillates in 1962, one of the most important chemical processes with a worldwide capacity of the order of 500 million t/a. Compared to the previously used amorphous silica-alumina catalysts, the zeolites were not only orders of magnitude more active, which enabled drastic process engineering improvements to be made, but they also brought about a significant increase in the yield of the target product, viz. motor gasoline. With the huge FCC capacity worldwide, the added value of this yield enhancement is of the order of 10 billion US $ per year. |

| zeolite molecular sieves structure chemistry and use: Handbook of Zeolites T. W. Wong, 2009 Zeolites are microporous crystalline solids with well-defined structures. Generally they contain silicon, aluminium and oxygen in their framework and cations, water and/or other molecules within their pores. Many occur naturally as minerals, and are extensively mined in many parts of the world. Others are synthetic, and are made commercially for specific uses, or produced by research scientists trying to understand more about their chemistry. Because of their unique porous properties, zeolites are used in a variety of applications with a global market of several million tonnes per annum. In the western world, major uses are in petrochemical cracking, ion-exchange (water softening and purification), and in the separation and removal of gases and solvents. Other applications are in agriculture, animal husbandry and construction. They are often also referred to as molecular sieves. This book presents leading research from around the world. |

| zeolite molecular sieves structure chemistry and use: Natural Zeolites G. Gottardi, E. Galli, 2012-12-06 Zeolites form a family of minerals which have been known since the 18th century, but they remained a curiosity for scientists and collectors until 60 years ago, when their unique physicochemical properties attracted the attention of many researchers. In the past 30 years there has been an ex traordinary development in zeolite science; six International Conferences on Zeolites have been held every 3 years since 1967, and a large number of interesting contributions have been published in their proceedings. Many books, written either by individual authors or by several authors under a leading editor, have been published on these interesting silicate phases, but none has been devoted specifically to natural zeolites, even though this theme may be of interest not only to earth scientists, but also to chemists, as the in formation obtained from natural samples completes and in tegrates the characterization of many zeolites. We are trying to fill this gap on the basis of 20 years of research on natural zeolites, which we performed at the University of Modena together with many friends and colleagues. If it is in general difficult to write a scientific book with out upsetting somebody, this is particularly true for a book on natural crystals, because mineralogy is an interdisciplin ary science which covers some fields of physics, chemistry, it is almost impossible to meet every petrology, geology, and requirement. |
| zeolite molecular sieves structure chemistry and use: Guidelines for Mastering the Properties of Molecular Sieves Denise Barthomeuf, E.G. Derouane, Wolfgang Hölderich, 2013-03-08 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 a characteristic feature and which explains the term of molecular sieves currently used to name these ma terials. Indeed, a large number of industrial processes for separation of gases and liquids, and for catalysis are based upon the use of this low dimensional feature in zeolites. For instance, zeolites constitute the first class of catalysts employed allover the world. Because of the peculiarity and flexibility of their structure (and composition), zeolites can be adapted to suit many specific and diversified applications. For this reason, zeolites are presently the object of a large and fast-growing interest among chemists and chemical engineers. |
