To leave our planet liveable in the next millennium mankind is forced to find environmentally friendly ways in solving the problems of everyday life. Among others, technologies of producing chemicals, absolutely necessary for maintaining a comfortable life, have to be modified, in some instances fundamentally changed now, or in the very near future.Developing new technologies requires strong and innovative fundamental research. In order to provide opportunity for crossfertilization the Federation of European Zeolite Associations (FEZA) decided to organise a conference, where researchers from academia as well as industry can meet, exchange ideas, show and discuss research efforts and results concerning the development of environmentally friendly processes and technologies.The conference, and thus the proceedings are divided into two main parts. The first part contains works concerning the synthesis, modification and characterisation of zeolitic materials as catalyst candidates in environmentally friendly technologies. Works in the second part describe various applications starting from developing highly selective reactions for the fine chemical industry, through waste-water treatment to applying zeolite for formulating bacteria for pest control.

ZEOCAT ''95 is the eleventh in the series of symposia devoted to special fields of zeolite chemistry. Six plenary lectures, forty oral and forty-two poster presentations were included in the program. The accepted papers cover every aspect of catalysis on microporous materials. A significant number of the contributions describe the synthesis, modification, instrumental and chemical characterisation of zeolites and other micro- and mesoporous materials. Catalytic reactions involve hydrocarbon cracking, nucleophilic aromatic substitution, methanol to hydrocarbon conversion, hydration of acetylene, various alkylation reactions, redox transformations, Claisen rearrangement, etc.

This book is a supplementary volume to J. Weitkamp et al. (Editors), Zeolites and Related Microporous Materials: State of the Art 1994 - Proceedings of the 10th International Zeolite Conference, Garmisch-Partenkirchen, Germany, July 17-22, 1994. The larger part of this supplementary volume contains full texts of the Recent Research Reports, which were presented as posters, and the discussions of all the lectures and posters. One full paper is included, because one page was missing in the version published in the Proceedings. A complete list of participants is also included.

These proceedings, comprising 7 plenary lectures, 100 oral and 175 poster presentations, reflect present activities in the field of microporous materials. The International Zeolite Conferences are devoted to all aspects of zeolite science and technology. The term zeolite is to be understood in its broadest sense comprising all kinds of crystalline microporous materials regardless of their composition (e.g. aluminosilicates and other metallosilicates, silica, aluminophosphates, gallophosphates etc.), occurring in nature or synthesized by man. Mesoporous silica, aluminosilicates and other metallosilicates, as recently discovered are also included. Zeolite catalysis continues to be an area of particular interest, not only the classical hydrocarbon conversions but also zeolite catalysis of oxidation reactions, formation of a greater variety of organic compounds and environmental catalysis. Much work has been done on the synthesis of zeolites and zeolite-like materials, which is reflected in the large number of contributions to these proceedings. Improvement of techniques for investigation has stimulated interest in adsorption and diffusion studies. Other areas enjoying increasing attention are modelling, theory, and novel materials.

Zeolites and related microporous materials are used in oil processing and in the fine and petrochemical industries on a large scale. New applications of zeolites contribute to environmentally friendly processes and refined zeolites such as catalytic zeolite membranes and zeolites containing exhaust-pipe reactors are being introduced. Recent diversity in zeolite research has been fueled by the increase in number of microporous materials and the combination with interfacing science areas. The possibility to accommodate ions, large molecules or nanostructures in the crystalline matrix has been explored and the performance of electronic, acoustic and photonic modified response of the materials has been tested.This volume provides up-to-date information on new zeolite and related materials and composites, their applications, testing of new processes and techniques, and promising laboratory results as well. A vast amount of work from a fundamental aspect is incorporated. In particular, the combination of science and application offers useful information for readers interested in molecular sieves.

This new book will be welcomed by companies involved in catalysis and catalyst manufacturing, sorbent and detergent production, chemical and petroleum refining, and by research scientists in academia. It contains 76 original contributions of recent work on fundamental and technological aspects of zeolite research and application. Particular attention is paid to novel developments in zeolite catalysis, sorption on zeolites and use of zeolites as detergent builders. Problems of zeolite synthesis, structure, modification, ion exchange, diffusion and novel applications are also dealt with. 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.
