Book excerpt: Ignorées du grand public, souvent mal connues des étudiants chimistes, les zéolithes synthétiques ont pourtant des qualités exceptionnelles. Belles par leurs cristaux microscopiques et le réseau régulier de leurs cages et canaux de taille moléculaire, elles sont capables de jouer les rôles les plus divers : échange d'ions, tamisage moléculaire, catalyse acide, basique, acidobasique, d'oxydoréduction, bifonctionnelle, etc. Leurs nombreuses applications les ont placées au cœur même de notre société. Tournez les pages de ce livre pour en juger. Le pétrole est trop lourd pour fournir directement carburants et lubrifiants de qualité pour nos déplacements et les éléments de base pour la fabrication des polymères, solvants... Les zéolithes sont là pour solutionner ces problèmes, catalysant économiquement et écologiquement craquage, hydrocraquage, isomérisation, alkylation, conversion du méthanol, etc. Remplaçant les solutions acides ou basiques corrosives et polluantes utilisées en chimie fine, catalysant la dépollution des rejets gazeux ou liquides, elles œuvrent pour une chimie plus propre. Catalyseurs modèles, les zéolithes ont permis une avancée importante vers une conception réellement scientifique des catalyseurs.

Book excerpt: As refiners worldwide meet crude oil quality problems and address environmental issues and regulations, development of new fluid catalytic cracking (FCC) formulations are essential. In this volume, theoretical and applied aspects of cracking are discussed in chapters dealing with the origin and effects of strong acidity, modelling, catalyst testing, residue processing, and additive usage. Several chapters combine catalyst design with modern characterization techniques to provide guidance in the difficult problem of cracking metal-contaminated feedstocks.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction to the design, synthesis, characterization, and catalytic properties of nanoporous catalysts for the biomass conversion With the specter of peak oil demand looming on the horizon, and mounting concerns over the environmental impact of greenhouse gas emissions, biomass has taken on a prominent role as a sustainable alternative fuel source. One critical aspect of the biomass challenge is the development of novel catalytic materials for effective and controllable biomass conversion. Edited by two scientists recognized internationally for their pioneering work in the field, this book focuses on nanoporous catalysts, the most promising class of catalytic materials for the conversion of biomass into fuel and other products. Although various catalysts have been used in the conversion of biomass-derived feedstocks, nanoporous catalysts exhibit high catalytic activities and/or unique product selectivities due to their large surface area, open nanopores, and highly dispersed active sites. This book covers an array of nanoporous catalysts currently in use for biomass conversion, including resins, metal oxides, carbons, mesoporous silicates, polydivinylbenzene, and zeolites. The authors summarize the design, synthesis, characterization and catalytic properties of these nanoporous catalysts for biomass conversions, discussing the features of these catalysts and considering future opportunities for developing more efficient catalysts. Topics covered include: Resins for biomass conversion Supported metal oxides/sulfides for biomass oxidation and hydrogenation Nanoporous metal oxides Ordered mesoporous silica-based catalysts Sulfonated carbon catalysts Porous polydivinylbenzene Aluminosilicate zeolites for bio-oil upgrading Rice straw Hydrogenation for sugar conversion Lignin depolymerization Timely, authoritative, and comprehensive, Nanoporous Catalysts for Biomass Conversion is a valuable working resource for academic researchers, industrial scientists and graduate students working in the fields of biomass conversion, catalysis, materials science, green and sustainable chemistry, and chemical/process engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Demands for a rapid and accurate analysis of some of the trace elements present in regenerated catalysts has led tothe use of a grinding-briquetting technque for the preparation of samples of regenerated petroleum cracking catalysts. The trace elements vanadium, chromium, iron, nickel, copper, zinc, lead, and rare earths, lanthanum, cerium, neodymium, may all be determined on the one sample. A more informative empirical formula for evaluating the level of trace metal contamination in regenerated stock is proposed. (Author).
