Since 1987, the Petroleum Division of the American Chemical Society (ACS) has sponsored at 3 year intervals an international symposium on fluid cracking catalysts (FCC) technology. This volume collects the recent progress of this technology as reported in the papers presented during the 232th National Meeting of the ACS in San Francisco, September 10-14, 2006. Sixty-six years after the introduction of the fluid cracking catalyst process, it remains the main process of gasoline generation for the estimated 237 millions cars on US roads. Catalysts testing and evaluation still remains a subject of interest, debate and controversy. Lambda sweep testing, testing of SOx, NOx and combustion promoters have been discussed in details together with catalyst evaluation for atmospheric residues and metal contaminated oils cracking. Of particular interest has been the introduction of novel concept in process design aimed at improving cracked product selectivity such as two-stage risers for better gasoline and olefins production and downer technology for high severity processes . The importance of solid state nuclear magnetic resonance (NMR) in the study of crude oils, catalysts and reaction products are illustrated by several examples. Two contributions describe the use of predictive methods to understand FCC aging and deactivation and personal overviews of the development of SOx and combustion promoters technology are presented. * Presents findings from the tri-annual international symposium on fluid cracking catalysts (FCC) technology, sponsored by the Petroleum Division of the American Chemical Society (ACS) * Two contributions describe the use of predictive methods to understand FCC aging and deactivation * Personal overviews by the authors of the development of SOx and combustion promoters technology

Unsteady-state operations of catalytic reactors provide plentiful opportunities for research and commercial realization of efficient heterogeneous catalytic processes. Forced unsteady state conditions generate unique distributions of process parameters and catalyst states often unattainable with traditional, steady-state operation. The unsteady-states can be created by periodic changes in input flow parameters, such as changes in inlet temperature and composition, catalyst circulation through reaction and regeneration zones, or periodic flow reversals through fixed catalyst bed. This can result in increased productivity, selectivity, capital savings and operating cost reduction (higher energy efficiency). Efficient environmental technologies for treatment of toxic emissions, acid rain and greenhouse gas emissions can also be developed using the unsteady-state concept. The Proceedings communicate recent progress in these areas of research and promote future development. The aims are to establish relations between academia, industry, engineers and scientists from all over the world, to stimulate new catalytic technologies as well as fundamental research, and to create new concepts for the development of effective catalytic systems. It presents the most up-to-date research in catalysis. - contains the most recent developments in catalytic research - includes research finding as well as their application to industry - a thorough source of information on the latest developments of industrial catalysis in Japan

The present book "Zeolites and Related Materials: Trends, Targets and Challenges" reports the communications that have been presented at the 4th International FEZA (Federation of European Zeolite Associations) Conference in Paris, September 3-6, 2008. It gives an excellent overview of the present state of the art of ordered nanoporous solids including zeolites as well as synthetic layered materials (clays), nanosized molecular sieves, ordered mesoporous solids, metal-organic-framework compounds (MOFs), carbons, etc. with emphasis on the synthesis, comprehensive characterization and advanced applications. The significant research activities in this domain are due to the outstanding properties of those nanoporous materials that concentrate the collaborative efforts of researchers from material science, chemistry, physical chemistry and physics. The understanding and development of the unique properties of porous materials relies on a unique blend of multidisciplinary knowledge covering material science, with the implication of organic and colloid chemistry, to prepare micro- and mesoporous materials; surface and adsorption sciences sustained by theory and modelling to understand the peculiar behaviour of molecules in confined systems; special branches of catalysis, physics, chemical engineering and life science to design novel applications. * This book summarizes the developments in the area of nanoporous solids at the dawn of the 21st century, useful for both students/young researchers entering the field of nanoporous materials, as well as for senior scientists * Also summarizes the new family of porous compounds, e.g. MOF's and ordered porous carbon * The present state-of-the-art and prospects of nanoporous solids for advanced applications is discussed

Past And Present In Denox Catalysis From Molecular Modelling To Chemical Engineering

This book offers an overview of the state of the art in the field of DeNOx catalysis in order to focus novel orientations, new technological developments, from laboratory to industrial scale. A particular attention has been paid towards the implementation of catalytic processes for minimising NOx emissions either from stationary or mobile sources under lean condition to meet future standard regulations of NOx emissions. In the first part of this book, critical aspects reported in the literature which usually make difficult the achievement of efficient catalytic technologies in those conditions are summarised and analysed in order two separate new perspectives. The second part deals with fundamental aspects at molecular level. A better understanding of the reactions involved under unsteady-state conditions is probably a pre-requisite step for improving the performances of the actual processes or developing original ones. The development of powerful in situ spectroscopic techniques is of fundamental interest for kinetic modelling. Correlations between spectroscopic and kinetic data with those obtained from theoretical calculations are reported. Some illustrations emphasise the fact that these comparisons may help in determining the nature of the catalytic active sites and building predictive tools for simulations under running conditions. The latter part of this book will be illustrated by different practical approaches covering various aspects related to the catalysts preparation and the development of alternative technologies which include industrial considerations. - New technological developments for investigating catalytic reactions in transient conditions (in situ and operando spectroscopic techniques) - Concerted approaches in DeNOx catalysis - How academic aspects (kinetic, in situ spectroscopic measurements) can provide useful information for practical applications - Comparison of different approaches provided by academic and industrial partners

Despite the advances in understanding the phenomena that occur on a catalyst surface, much of the successful catalyst development and use continues to be half science and half art. The art resides in the practical knowledge of experts in the development and use of commercial catalysts-it comes with experience. Now the background needed to nurture the experience and inspire the art is collected along with the science into a single volume. Whether called upon to select or improve a catalyst, design a process, diagnose operating problems, or improve existing processes, the Handbook of Commercial Catalysts provides the information needed to form a basis for the task. It offers a starting point by providing a broad overview of 150 major commercial processes and the heterogeneous catalyst used for each. The author has arranged them according to specific reaction or reaction type, and supplies reference citations for deeper research. He offers valuable insghts-based on chemistry, thermodynamics, and surface science-that provide a framework for rational reasoning about catalyst performance. With data collected from the existing literature, from the in-house specialists of commercial vendors, and from his own extensive experience, the author discusses for each reaction: Product uses Chemistry Mechanism Catalyst type Catalyst suppliers and licensors Catalyst deactivation Catalyst regeneration Process units Process kinetics Armed with this information, the reader can begin rational analysis of an existing or planned reaction system and logically discuss catalyst characteristics and operations with technical representative of catalyst manufacturers and with colleagues.
