This volume looks at the recent progress of this technology as reported in the 21 papers presented during the 219th National Meeting of the ACS in New York, September 5-11, 2003. In addition, the volume focuses on the use of modern spectroscopic techniques for the generation of detailed structural analysis required for the advancement of the science of FCC design. Other chapters look at the use and importance of solid state nuclear magnetic resonance (NMR), microcalorimetry and atomic force microscopy (AFM) to the study of FCCs and discussing strategies to control pollutant emissions from a refinery FCCU and looking at advances in FCC preparation.

Catalyst production for the transformation of crudes into gasoline and other fuel products is a billion dollar/year business and fluid cracking catalysts (FCCs) represent almost half of the refinery catalyst market. During the cracking reactions, the FCC surface is contaminated by metals (Ni, V, Fe, Cu, Na) and by coke deposition. As a result, the catalyst activity and product selectivity is reduced to unacceptable levels thus forcing refiners to replace part of the recirculating equilibrium FCC inventory with fresh FCC to compensate for losses in catalyst performance. About 1,100 tons/day of FCC are used worldwide in over 200 fluid cracking catalyst units (FCCUs). It is for these reasons that refiners' interest in FCC research has remained high through the years almost independantly, of crude oil prices. However, recent oil company mergers and the dissolution of research laboratories, have drastically decreased the number of researchers involved in petroleum refining research projects; as a result the emphasis of research has shifted from new materials to process improvements and this trend is clearly reflected in the type of papers contained in this volume. Modern spectroscopic techniques continue to be essential in the understanding of catalyst performance and several chapters in the book describe the use of 27Al, 29Si and 13C NMR to study variation in FCC acidity during aging and coke deposition. In addition several chapters have been dedicated to the modeling of FCC deactivation, and to the understanding of contact times on FCC performance. Refiners efforts to conform with environmental regulations are reflected in chapters dealing with sulfur removal, metals contaminants and olefin generation.

The primary focus of this book as a whole is on performance - performance of the catalyst, of its surface, of the FCC unit, of the feedstocks employed, of the analytical methods used to characterize the catalysts, and of environmentally directed regulations that govern the production of transportation fuels from petroleum. The emphasis on catalyst performance, particularly commercial performance, essentially dictated that the chapter authors be experienced industrial catalytic chemists and engineers. However, each author approached the task with a clear-cut obligation to connect the roots of the science of FCC catalysis with the technology. Fluid Catalytic Cracking: Science and Technology has been written for workers in industrial catalysis and academia, including graduate students in chemistry or chemical engineering who are interested in acquiring an overall knowledge of one of the world's most important areas of catalysis. The book is concise, each topic is treated briefly; complete, all aspects of FCC catalysis are covered; and clear, anyone involved in this field will find topics of interest.

Hydrocarbons and their transformations play major roles inchemistry as raw materials and sources of energy. Diminishingpetroleum supplies, regulatory problems, and environmental concernsconstantly challenge chemists to rethink and redesign theindustrial applications of hydrocarbons. Written by NobelPrize-winner George Olah and hydrocarbon expert ÁrpádMolnár, the completely revised and expanded Second Edition ofHydrocarbon Chemistry provides an unparalleled contemporaryassessment of the field, presenting basic concepts, currentresearch, and future applications. Hydrocarbon Chemistry begins by discussing the general aspects ofhydrocarbons, the separation of hydrocarbons from natural sources,and the synthesis from C1 precursors with recent developments forpossible future applications. Each successive chapter deals with aspecific type of hydrocarbon transformation. The Second Editionincludes a new section on the chemical reduction of carbondioxide–focusing on catalytic, ionic, electrocatalytic,photocatalytic, and ezymatic reductions–as well as a newchapter on new catalysts and activation methods, combinatorialchemistry, and environmental chemistry. Other topics coveredinclude: Major processes of the petrochemical industry, such ascracking, reforming, isomerization, and alkylation Derivation reactions to form carbon-heteroatom bonds Hydrocarbon oxidations Metathesis Oligomerization and polymerization of hydrocarbons All chapters have been updated by adding sections on recentdevelopments to review new advances and results. Essential readingfor practicing scientists in industry, polymer and catalyticchemists, as well as researchers and graduate students, HydrocarbonChemistry, Second Edition remains the benchmark text in itsfield.

The Zeolites and Mesporous Materials at the Dawn of the 21st Century Proceedings are the expression of the oral and poster communications which where presented during the 13th International Zeolite Conference (IZC). They are subdivided into 32 thematic sessions starting from the genesis of materials to their applications through their characterisation. The paper volume contains the full texts of the 5 plenary and 6 keynote lectures and informative summaries of 150 oral and 540 poster presentations. These contributions have been selected among the 903 submissions received from a total of 57 countries! In order to gather all the communications in a handy document, the full texts of oral and poster presentations are available in CD-ROM. Besides the fields of zeolite science always represented at IZC (synthesis, characterisation, catalysis, etc¿), some subjects strengthened their position (mesoporous materials, theory and modelling), new areas emerge (advanced materials, environmental and life sciences) and older ones regain interest (natural zeolites). The understanding and development of the unique properties of porous materials relies on a unique blend of multidisciplinary knowledge: material science, with the implication of organic and colloid chemistry, to prepare micro- and mesoporous materials, surface and adsorption science 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. The gathering of these elements is at the basis of a fruitful and evolutionary zeolite science, as it is hopefully reflected by these proceedings.

Chemists today are under the gun to find solutions to a host of tough new challenges, including diminishing oil reserves, an array of environmental hazards, and ever more stringent government regulations. Now this book helps meet these challenges by bringing together, for the first time in one volume, all major aspects of contemporary hydrocarbon chemistry. Hydrocarbon Chemistry functions equally well as a working professional reference and an advanced-level student text. Each of its twelve chapters treats a specific type of hydrocarbon transformation and reviews, in depth, all related basic chemistry-including reactivity, selectivity, stereochemistry, and numerous mechanistic aspects-as well as a wide range of practical applications. Offers comprehensive coverage of the chemistry of alkanes, cycloalkanes, alkenes and dienes, acetylenes, and aromatics Includes developments in the field through early 1994 Treats all important aspects of the chemistry involved in hydrocarbon transformations Emphasizes the chemistry of processes used in the petrochemical industry, including cracking, reforming, isomerization, and alkylation Reviews, in detail, derivation reactions to form carbon heteroatom bonds as well as both traditional and recent hydrocarbon oxidation techniques Numerous formulas and flowsheets help illuminate all important concepts and practical processes discussed Destined to be the definitive work on the subject well into the twenty-first century, Hydrocarbon Chemistry is an indispensable resource for chemical and petroleum engineers; industrial researchers in organic, physical organic, and inorganic chemistry; and students of those and other related disciplines.
