Book Description
This volume constitutes the proceedings of the second symposium on Catalysis and Automotive Pollution Control. CAPoC 2 was a great success from the point of view of its scientific interest, as evidenced by the content of this book, and also from the high participation, some 260 scientists. About two-thirds of the contributors came from the industrial world, mainly the car and oil industries and catalyst manufacturers. This is ample proof that exhaust catalysis remains a major topic of interest. The first part of the book is a general introduction to the problem of automotive pollution. The second, strictly catalytic, part is devoted to fundamental and applied studies on pollution control, with emphasis on exhaust catalytic converters.

Book Description
The proceedings of ZEOCAT 90 reflect the wide-ranging aspects of the rapidly expanding field of zeolite science and technology. The invited plenary lectures given by eminent zeolite scientists summarize current knowledge and address topical areas of zeolite research, including a contribution on the use of zeolites as membranes. The field of investigations described in the submitted articles in this volume covers a wide area of problems ranging from the influence of the synthesis process on the properties to questions of acidity, adsorption, diffusion, and catalysis. Of special interest are the newly developed applications of zeolites in the synthesis of fine chemicals, the use of zeolites for sensors and solid electrolytes, and the sophisticated zeolite-based separation processes.

Book Description
The organizers of this Fifth Symposium maintained their initial objectives, namely to gather experts from both industries and universities to discuss the scientific problems involved in the preparation of heterogeneous catalysts, and to encourage as much as possible the presentation of research work on catalysts of real industrial significance. Another highlight of these symposia was to reserve a substantial part of the program to new developments in catalyst preparation, new preparation methods and new catalytic systems. The fact that chemical reactions which were hardly conceivable some years ago have become possible today through the development of appropriate catalytic systems proves that catalysis is in constant progress.The papers in this volume deal with studies of unit operations in catalyst preparation, catalyst preparation via the sol-gel route, preparation of catalysts from layered structures and pillaring of clays, preparation and modification of zeolite-based catalysts, carbon supported catalysts, preparation of oxidation catalysts and novel and unusual preparation methods.

Book Description
Structure plays an important role in heterogeneous catalysis. It provides a framework for the arrangement and stragetic placement of key catalytic elements, hosting them in a prescribed manner so that their respective electronic properties can exhibit their desired catalytic functions and mutual interactions. Under reaction conditions these framework structures and their catalytic guests undergo dynamic processes becoming active participants of the overall catalytic process. They are not mere static geometric forms. The dynamics of catalytic structures are particularly vivid in selective oxidation catalysis where the lattice of a given catalytic solid partakes as a whole, not only its surface, in the redox processes of the reaction. The catalyst becomes actually a participating reagent. By proper choice of key catalytic elements and their host structures, preferred catalytic pathways can be selected over less desired ones. However, not only in selective redox catalysis does structure play an important role, its importance is also well documented, among others, in shape selective zeolite catalysis, enantioselective hydrogenation and hydrodesulfurization. The contributions presented in this book address the dynamic character of the solid state under catalytic reaction conditions. By relating structure to activity and selectivity in heterogeneous catalysis our understanding of such correlations has been significantly enhanced through the use of sophisticated spectroscopic means, surface science and modeling.

Book Description
The present volume concentrates on catalyst surfaces. The interaction of adsorbed molecules, mostly on heterogenous catalysts, although some reference to model catalysts is also made, is discussed here. Vibrational (infrared and electron energy loss spectroscopies, magnetic resonances (nuclear and electron spin) and thermal desorption methods have been included in this latter category. The reader will find also a comparison of these well established methods with their recent developments which make them much more attractive. Therefore, researchers working in the catalysis field will find much to interest them in this book.

Book Description
Catalyst Deactivation 1991 was an expanded version of earlier, highly successful symposia. The symposium featured invited and solicited papers including 4 plenary lectures, 78 oral presentations and 23 poster papers. Most of the papers are contained in this volume.The eight main topics emphasised at this most recent symposium were: deactivation mechanisms/phenomena (carbon deposition, poisoning, and sintering), methods (modeling and techniques), and important catalysts (hydrotreating, oxides, and zeolites). All of these areas were well represented as attested by the substantial number of papers contained in these proceedings. Four review papers based on the plenary lectures provide state-of-the-art perspectives on new thrusts in deactivation research and development.

Book Description
The 2nd International Symposium on Hydrotreatment and Hydrocracking of Oil Fractions, which is also the 7th in the series of European Workshops on Hydrotreatment, took place in Antwerpen, Belgium from November 14 to 17. The Symposium emphasized how oil refining faces increasingly severe environmental regulations. These and the increasing application of heavier crudes containing more S-, N- and metal components call for more efficient hydrotreatment and hydrocracking processes. It is clear from the keynote lectures, the oral contributions and the posters of this meeting that adapting the operating conditions will not suffice. Adequate catalysts need to be developed, with different composition and structure. Surface science techniques and molecular modeling are now well established tools for such a development. They should be of help in widely different aspects, like the role of precursors in the preparation or the modifications undergone by the catalyst under reaction conditions. The improvement of hydrotreatment and hydrocracking also needs accurate modeling of the chemical reactor. This requires more representative hydrodynamics and kinetic models whose validity extends to the very low S- and N-contents. These areas should be vigorously developed.

Book Description
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 second 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. The book gives an overall view of the problems encountered by academic and industrial researchers. A large variety of reactions are described, the emphasis being on selectivity: chemo-, regio-, stereoselectivity (even enantioselectivity) and on the change of these selectivities as a function of the characteristics of the surface sites (nature, distribution, etc.).The three themes of the symposium, hydrogenation, oxidation and acid-base catalysis were introduced in four plenary lectures and two invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers selected by the Scientific Committee were presented. All are reproduced in full in this proceedings volume.
