This book was released on 1999 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ANHYDRIDE MALEIQUE EST UN IMPORTANT INTERMEDIAIRE INDUSTRIEL. L'AMELIORATION DU RENDEMENT POUR L'OXYDATION PARTIELLE DU BUTANE EN AM PRESENTE DONC UN GRAND INTERET. L'OBJECTIF DE CE TRAVAIL EST D'ETUDIER LA REACTION DANS UN NOUVEAU TYPE DE REACTEUR : LE REACTEUR MEMBRANAIRE. LA MEMBRANE CONTROLE L'APPORT D'OXYGENE VERS LE LIT CATALYTIQUE, CE QUI PERMET DE TRAVAILLER AVEC DES CONCENTRATIONS ELEVEES EN BUTANE, LIMITANT AINSI L'OXYDATION TOTALE. DES CATALYSEURS V-P-O TESTES DANS UN REACTEUR CONVENTIONNEL SOUS CONDITIONS REDUCTRICES (O 2/C 4 = 0.6) METTENT EN EVIDENCE UNE RAPIDE CHUTE DE LA PRODUCTION EN AM PROVOQUEE PAR UNE REDUCTION DU CATALYSEUR. L'ACTIVATION DU BUTANE A LIEU SUR DES SITES V 4 + TANDIS QUE LES SITES V 5 + SONT RESPONSABLES DE LA FORMATION D'AM. LA DESACTIVATION DU BUTANE EST LIMITEE LORSQUE LE CATALYSEUR EST PREALABLEMENT OXYDE A 500\C. DES CATALYSEURS V-P-O DOPES PAR DU MOLYBDENE OU PAR DU COBALT DEVIENNENT SELECTIFS EN ANHYDRIDE MALEIQUE SOUS CONDITIONS REDUCTRICES. LES DEUX ELEMENTS AGISSENT SUR L'EQUILIBRE REDOX DES ESPECES VANADIUM ET PERMETTENT DE CONSERVER UNE MEILLEURE CAPACITE OXYDANTE. L'ETUDE DE LA REACTION EN REACTEUR MEMBRANAIRE A MIS EN EVIDENCE L'HETEROGENEITE DU LIT CATALYTIQUE. L'APPORT D'OXYGENE DANS LE COMPARTIMENT INTERNE AVEC LE BUTANE REND LE CATALYSEUR PLUS SELECTIF. L'INVERSION DU FLUX INTERNE PERMET D'HOMOGENEISER L'ETAT DU CATALYSEUR ET D'OBTENIR TEMPORAIREMENT DES PERFORMANCES CATALYTIQUES SUPERIEURES AU REACTEUR CONVENTIONNEL.

Download or read book Advanced Heterogeneous Catalysts Volume 1 written by Sudarsanam Putla and published by ACS Symposium. This book was released on 2021-05-07 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances and applications of nanosized catalysts Over the last five years, tremendous advances have been made in heterogeneous catalysis. In particular, catalysts' design from the bulk to nano-scale (1-100 nm), with desirable active sites, has received great attention in current catalysis research with the aim to fill the gap between homogeneous and heterogeneous catalysis. This volume focuses on applications of nanosized catalysts. Articles describe characterization, synthesis, and applications in biomass conversion, auto-exhaust purification, selective oxidation/hydrogenation, syngas conversion, and other important reactions. Readers will find examples of catalysts designed to be tunable for specific outcomes, inspiring their research. Scientists and engineers in chemistry, materials science, nanotechnology, and chemical engineering will find this volume useful.

Available in PDF, EPUB and Kindle. Book excerpt: The most current guide to solid state polymerization Solid State Polymerization (SSP)is an indispensable tool in the design, manufacture, and study of polymers, plastics, and fibers. SSP presents significant advantages over other polymerization techniques due to low operating temperatures, inexpensive equipment, and simple and environmentally sound procedures. Combining fundamentals of polymer science, chemistry, physical chemistry, and engineering, SSP also offers many research applications for a wide range of students and investigators. Gathering and filtering the latest literature on SSP, Solid Solid State Polymerization offers a unique, one-stop resource on this important process. With chapters contributed by leaders in the field, this text summarizes SSP, and provides essential coverage that includes: An introduction to SSP, with chemical and physical steps, apparatus, advantages, and parameters SSP physical chemistry and mechanisms Kinetic aspects of polyesters and polyamides SSP Catalysis in SSP processes Application of SSP under high pressure conditions in the laboratory Engineering aspects regarding process modeling and industrial application Recent developments and future possibilities Solid State Polymerization provides the most up-to-date coverage of this constantly developing field to academic and industry professionals, as well as graduate and postgraduate-level students in chemical engineering, materials science and engineering, polymer chemistry, polymer processing and polymer engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
