Book Description
The implementation of hydrogen production processes on an industrial scale requires a comprehensive understanding of the chemical proprieties of catalytic materials and the applications such materials in electrocatalysis. This volume presents information about catalytic materials for hydrogen production and hydrogen valorization in electro-oxidation reactions. Chapters emphasize on materials for classical steam, CO2 sorption enhanced steam reforming and dry reforming for hydrogen production. The hydrogen electro-oxidation reaction in anodes of Solid Oxide Fuel Cells (SOFCs) is also explained. Chapters have been contributed by experts in industrial chemistry, adding a valuable perspective for readers. This volume is essential to chemical engineering researchers and industrial professionals interested in hydrogen production systems and the science behind the materials driving the reactions in key processes.

Book Description
In the last decade there have been numerous advances in the area of rhodium-catalyzed hydroformylation, such as highly selective catalysts of industrial importance, new insights into mechanisms of the reaction, very selective asymmetric catalysts, in situ characterization and application to organic synthesis. The views on hydroformylation which still prevail in the current textbooks have become obsolete in several respects. Therefore, it was felt timely to collect these advances in a book. The book contains a series of chapters discussing several rhodium systems arranged according to ligand type, including asymmetric ligands, a chapter on applications in organic chemistry, a chapter on modern processes and separations, and a chapter on catalyst preparation and laboratory techniques. This book concentrates on highlights, rather than a concise review mentioning all articles in just one line. The book aims at an audience of advanced students, experts in the field, and scientists from related fields. The didactic approach also makes it useful as a guide for an advanced course.

Book Description
The catalytic cooligomerizations of olefins are among the most important C-C coupling reactions. Many transition metals have been used as catalysts for this kind of reactions. They are rhodium, ruthenium, nickel, cobalt, palladium and iron etc.. In this paper the rhodium catalyzed cooligomerizations of ethylene and conjugated dienes were mainly studied. Rhodium catalyzed cooligomerization of ethylene with dienes gives versatile products with wide industrial applications. • For example, rhodium catalyzed cooligomerization of ethylene and 1,3-butadiene produces 1,4-hexadiene with a high selectivity to its trans-form, which is an important intermediate for the synthesis of EPDM (Ethylene-Propylene-Diene-Monomer). • Rhodium catalyzed cooligomerization of ethylene with conjugated methyl linoleate yields the branched and unsaturated fatty substances. The linoleate is a fatty substance direct from nature and sustainable resources. The branched fatty products and their derivatives possess low melting points and pour points, which have attractive prospects of applications in lubricants, cosmetics and some other industrial fields. • The rhodium catalyzed cooligomerization of ethylene and styrene affords 3-phenyl- 1-butene and serves as a model reaction for the synthesis of compounds with pharma- cological activity.

By using PEG1000/water solvent systems selective synthesis of trans-1,4-hexadiene has been achieved under moderate reaction conditions. PEG1000 based novel temperature-dependent multi-solvent systems were developed for the reac- tion of ethylene and conjugated methyl linoleate. Some poly-ether modified phosphorous ligands were synthesized and used to condition the product selectivity and suppress the catalyst leaching. Cinnamyl chloride was used as catalyst promoter and was found to be very effective in reactivating the decayed rhodium catalysts. More interesting is that the addition of this organic chloride largely enhanced the activity of rhodium catalysts in the reaction of ethylene and styrene.

Book Description
Metal-Support and Metal-Additive Effects in Catalysis, Volume 11, documents the proceedings of an international symposium organized by the Institut de Recherches sur la Catalyse - CNRS - Villeurbanne and sponsored by the Centre National de la Recherche Scientifique, Ecully (Lyon), September 14-16, 1982. This volume contains 40 manuscripts that cover a wide range of topics. Among these are studies of metal-support interactions involving Pt/Al2O3, Pt/TiO2,Fe/TiO2, Pt/MgO, Rh /Al2O3, and Pt/CeO2 catalysts. There are also separate chapters dealing with ethane, n-butane, and cyclohexane hydrogenolysis; skeletal isomerization of methylpentanes; the catalytic activity and selectivity of noble metals; CO hydrogenation over supported on SiO2, Al2O3, Ti O2,and Zr O2 nickel catalysts; and the role of promoters in Pd catalysts for methanol synthesis. Subsequent chapters cover the poisoning of platinum and nickel by sulfur; C6H6 and CO chemisorption on Pt78Ni22 (111) single crystal alloy; the surface composition of industrial ammonia synthesis catalysts; and the role of alkalis and electronegative promoters on Fe and Ni catalysts.
