    • Volumen 51
    • K. Tanabe + 3 más
    • Inglés
    This volume summarises and reviews the enormous progress made over the past two decades in solid acids and bases, with emphasis on fundamental aspects and chemical principles. In recent years many new kinds of solid acids and bases have been found and synthesized. The surface properties (in particular, acidic and basic properties) and the structures of the new solids have been clarified by newly developed measurement methods using modern instruments and techniques. The characterized solid acids and bases have been applied as catalysts for diversified reactions, many good correlations being obtained between the acid-base properties and the catalytic activities or selectivities. Recently, acid-base bifunctional catalysis on solid surfaces is becoming a more and more important and intriguing field of study.It has been recognized that the acidic and basic properties of catalysts and catalyst supports play an important role in oxidation, reduction, hydrogenation, hydrocracking, etc. The effect of the preparation method and the pretreatment conditions of solid acids and bases on the acidic and basic properties, the nature of acidic and basic sites and the mechanism regarding the generation of acidity and basicity have been elucidated experimentally and theoretically. On the basis of the accumulated knowledge of solid acids and bases, it is now possible to design and develop highly active and selective solid acid and base catalysts for particular reactions. The chemistry of solid acids and bases is now being related to and utilized in numerous areas including adsorbents, sensors, cosmetics, fuel cells, sensitized pressed papers, and others. The information presented in this book will therefore be of interest to a wide-ranging readership.

    The production of useful materials and the removal of polluting substances are fundamental to chemical technology, and in this respect catalytic and separation processes play essential roles. In order to cope with increasing demands to find solutions for the shortage of natural resources and global environmental pollution, rapid and significant progress in the technology is required.This book results from the successful seminar on Selective Reactions and Separation, held at Oiso, Japan, in February 1988. The seminar was organised by ASPRONC (the Association for the Progress of New Chemistry) as the fourth in a series of seminars on Frontier Technology. ASPRONC was inaugurated in 1986 and its membership comprises major companies in the chemical industry and various other sectors interested in chemistry. The aim of this seminar was to explore the frontiers of catalytic and separation technology and to discuss the requirements for its future development. The many interesting lectures and active discussions which resulted stimulated the editors to prepare this book. Each lecturer has written a chapter which represents a significantly revised and extended version of his original lecture.The book will appeal to many readers and will undoubtedly help to make a positive contribution to the future development of chemical technology.

    • Inglés
    Between the area known as surface science (which mainly deals with single crystal surfaces) and the vast area of the surface properties of dispersed solids (knowledge of which is widely applied in catalysis and materials science) there is still a remarkably wide, although gradually decreasing, gap. Because fundamental physico-chemical problems are involved, this borderline area needs to be explored. With this objective, the Trieste meeting brought together specialists with a variety of origins and backgrounds, with the aim of stimulating the growth of our knowledge in this area.This proceedings volume contains ninety-three papers, comprising plenary lectures, short communications, and poster contributions on the applications of physical and theoretical methods to perfect and dispersed (microcrystalline and amorphous) metals, oxides, and mixed systems. Special emphasis is given to metal-support interfaces.The book thus provides a wealth of up-to-date information on a topic of current interest which will be of value to researchers who use chemical and/or physical methods for the study of surfaces.

  • An Introduction to Rheology

    • 1 Edición
    • Volumen 3
    • K. Walters
    • Inglés
    Rheology is, by common consent, a difficult subject and some of the theoretical components are often viewed as being of prohibitive complexity by scientists without a strong mathematical background. There are also the difficulties inherent in any multidisciplinary science like rheology for those with a specific training. Therefore, newcomers to the field are sometimes discouraged, and for them the existing texts on the subject - some of which are outstanding - are of limited assistance because of their depth of detail and highly mathematical nature.This book introduces the subject of rheology in terms understandable to non-experts and describes the application of rheological principles to many industrial products and processes. It provides a simple but authoritative guide which shows clearly how mathematics, physics and chemistry have contributed to the development of rheology. The generic features of all liquid-like materials are summarised, i.e. viscosity, linear viscoelasticity, normal stresses and extensional viscosity. Particular systems are then discussed, i.e. polymeric liquids and suspensions. The final chapter gives an outline of the theoretical advances which have been made. Consistent notation and nomenclature have been used throughout the book, and the key textbooks and publications which will enable the reader to follow up particular topics are listed.

Topics which are the subject of much current interest are also treated, e.g. new catalytic applications of zeolites in the synthesis of fine chemicals, novel formulations of detergent builders and industrially developed zeolite-based separation processes. The application of zeolites is also discussed from both economic and ecological points of view. The contributions cover a wide range of materials and results which are organised, to a large extent, in tables and figures and are identified by appropriate keywords.The meeting at which these contributions were presented was the latest in a series of smaller, more specialized zeolite meetings which are held in between the large International Zeolite Conferences. Participating in the symposium were experts from both industry and academia who gave invited lectures, oral and poster presentations. The resulting book provides a large body of helpful information for present and future work and development in zeolite research and applications.

  • Transition Metal Oxides

    Surface Chemistry and Catalysis
    • 1 Edición
    • Volumen 45
    • H.H. Kung
    • Inglés
    In this book the author presents an up-to-date summary of existing information on the structure, electronic properties, chemistry and catalytic properties of transition metal oxides.The subjects covered in the book can be divided into three sections. The first (chapters 1 to 3) covers the structural, physical, magnetic, and electronic properties of transition metal oxides. Although the emphasis is on surface properties, relevant bulk properties are also discussed. The second section (chapters 4 to 7) covers surface chemical properties. It includes topics that describe the importance of surface coordinative unsaturation in adsorption, the formation of surface acidity and the role of acidity in determining surface chemical properties, the nature and reactivities of adsorbed oxygen, and the surface chemistry in the reduction of oxides. The third section (chapters 8 to 14) is on the catalytic properties. Various catalytic reactions including decomposition, hydrogenation, isomerization, metathesis, selective oxidation, and reactions involving carbon oxides are discussed. Emphasis is placed more on reaction mechanisms and the role of catalysts than on kinetics and processes. Chapters on the preparation of oxide catalysts and on photo-assisted processes are also included. Whenever appropriate, relationships between various topics are indicated.Written for surface physicists, chemists, and catalytic engineers, the book will serve as a useful source of information for investigators and as a comprehensive overview of the subject for graduate students.

    • Inglés
    The recession in the traditional heavy industries along with the development of advanced technologies in all the industrial countries has meant that the impact of heterogeneous catalysis in the synthesis of fine chemicals is becoming increasingly noticeable. The first International Symposium on Heterogeneous Catalysis and Fine Chemicals is to be seen in this perspective. Organised by the Laboratory of Catalysis in Organic Chemistry of the University of Poitiers within the framework of the International Symposia of the `Centre National de la Recherche Scientifique' (CNRS), the symposium provided an opportunity for contact between academic researchers and manufacturers, users (or potential users) of solid catalysts for fine chemical synthesis.Two panels of industrial and academic researchers - one on selective hydrogenation, the other on selective synthesis of substituted aromatics - showed that heterogeneous catalysis already plays a significant role in fine organic chemistry. The main topics of the symposium were introduced in six plenary lectures and three invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers were submitted from which the Scientific Committee selected the 35 communications (oral or poster) which fitted most closely the theme of the symposium. All are reproduced in full in this Proceedings volume.

  • Characterization of Porous Solids

    • 1 Edición
    • Volumen 39
    • H. Kral + 3 más
    • Inglés
    The importance of porosity has long been recognized by scientists and engineers. Porous solids are widely encountered in industry and everyday life and their behaviour, e.g. chemical reactivity, adsorptive capacity, and catalytic activity is dependent on their pore structure. A considerable amount of work on porous solids has been undertaken both in academic and in industrial laboratories. However, all this activity is in urgent need of a critical appraisal. To undertake this task, a number of leading experts in the field of adsorption, porosimetry, X-ray and neutron scattering, optical and electron microscopy, calorimetry and fluid permeation, were brought together at the 1987 IUPAC (COPS I) Symposium.This proceedings volume provides an up-to-date overall review of the theoretical foundations for modelling and characterizing porous systems. It deals with most of the techniques in current use as applied to both model systems and porous solids of industrial importance. The reader will find the description and discussion of a number of novel techniques as well as a critical appraisal and comparison of the more established methods. All those concerned with the characterization of porous solids in academic and industrial laboratories will find much to interest them in this volume. It should be on the bookshelf of applied research centres involved in adsorption, catalysis, purification of gases and liquids, pigments, fillers, building materials, etc.

This book will be extremely useful in evaluating and deciding which evaporation technology will meet a particular set of requirements.

  • Catalyst Deactivation 1987

    • 1 Edición
    • Volumen 34
    • G.F. Froment + 1 más
    • Inglés
    This Symposium on Catalyst Deactivation ensues those held at Berkeley (1985), Antwerp (1980) and Berkeley (1978).The three main topics emphasised at this most recent symposium were: the techniques used in deactivation studies, the mechanisms of catalyst deactivation, and modelling. With respect to the first, it became apparent that the study of deactivation faces even more difficulties than the characterization of fresh catalysts and the measurement of activity or selectivity, due to the multiplicity of interacting processes occurring during deactivation. Quite substantial progress has been made recently in the understanding of the mechanisms of various deactivation processes, particularly coking, and extra time was accorded to these topics at the symposium. The third topic corresponds to a problem which is very central to development studies and to the chemical engineering aspect of catalysis: it deals with the representativity of accelerated tests and the modelling of the deactivation phenomena.

    In June 1984 the EEC Commission proposed new standards of permissible exhaust gas from motor vehicles to be introduced in Europe; these standards were approved by the Ministers of the Environment one year later. As the control of automotive pollution is at present mainly a catalytic problem, it was decided to hold an International Symposium on the subject, and an organizing committee composed of people engaged in catalytic research in the different Belgian Universities was constituted. This was the first Symposium of its kind to be held on an international level, and the quality and scientific interest of the papers presented was exceptional. It is planned to hold a follow-up Symposium in 2 to 3 years' time.The first part of the book is a general introduction to the problem of automotive pollution. The second, properly catalytic, part is devoted to fundamental and applied studies on pollution control, with emphasis on exhaust catalytic converters.

    The collection of contributions in this volume presents the most up-to-date findings in catalytic hydrogenation. The individual chapters have been written by 36 top specialists each of whom has achieved a remarkable depth of coverage when dealing with his particular topic. In addition to detailed treatment of the most recent problems connected with catalytic hydrogenations, the book also contains a number of previously unpublished results obtained either by the authors themselves or within the organizations to which they are affiliated.Because of its topical and original character, the book provides a wealth of information which will be invaluable not only to researchers and technicians dealing with hydrogenation, but also to all those concerned with homogeneous and heterogeneous catalysis, organic technology, petrochemistry and chemical engineering.

    This book covers the proceedings of a symposium which was attended by researchers from all over the world who reported on and discussed recent advances in the field of catalytic polymerization of olefins.Over two decades have elapsed since the discovery of the Ziegler-Natta catalyst. Tremendous research effort has been aimed at improving this marvelous catalyst. In twenty-five years since the first publication, more than 15,000 papers and patents on the subject and on related subjects have appeared. This effort has yielded new generations of Ziegler-Natta catalysts with superior activity and stereospecificity. The complexities arising from the heterogeneity of the catalyst, however, have hindered understanding of the catalytic processes which take place on the catalyst surface. Nevertheless, many fundamental features of the catalyst system have now been clarified reasonably well. Recently a highly active homogeneous catalytic system has been developed, which is capable of catalyzing even isotactic polymerization of propene. There is no doubt that this finding will not only contribute to our understanding of the detailed mechanism of polymerization but also stimulate the development of various kinds of tailored polymers. Thus this subject will remain of paramount importance in the development of chemistry and polymer science for a long time to come.

    The Symposium was held to honour the memory of the late Dr. A.J. Tench who made numerous important contributions to our knowledge of the structure, reactivity and adsorption properties of oxide surfaces. This volume contains an up-to-date picture of adsorption and catalysis on oxide surfaces, not in the form of a comprehensive review but in its living aspects of work in progress. It describes detailed studies on the determination of the coordination surface ions, particularly oxide ions, by photoluminescence and reflectance spectroscopy, on the identification of adsorbed species by magnetic optical or surface techniques and on catalysis, with emphasis on new concepts such as catalysis involving excited states or structure sensitive reactions.Profession... working in the industrial and academic laboratories will find the book particularly useful as it provides a state-of-the-art account of our understanding of the structure and adsorption characteristics of oxide surfaces. Contained in the book are first class research papers by leading exponents in this field. A very important issue is that the book highlights for the first time the importance of excited states and structure sensitivity in determining the behaviour of oxide surfaces.

    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.

    Energy Conservation in the Process Industries provides insight into ways of identifying more important energy efficiency improvements. This book demonstrates how the principles can be employed to practical advantage. Organized into 12 chapters, this book begins with an overview of the energy situation and a background in thermodynamics. This text then describes a staged method to improved energy use to understand where the energy goes and how to calculate the value of losses. Other chapters consider improving facilities based on an understanding of the overall site energy system. This book discusses as well the fundamental process and equipment improvements. The final chapter deals with systematic and sophisticated design methods as well as provides some guidelines and checklists for energy conservation items. This book is a valuable resource for mechanical, lead process, and plant engineers involved in energy conservation. Process designers, plant managers, process researchers, and accountants will also find this book extremely useful.
