Book excerpt: The selective hydrogenation of butyronitrile to n-butylamine over Raney catalysts was tested in a high-pressure, three-phase reactor. ATR-IR technique was used to follow in-situ the hydrogenation of butyronitrile. INS spectroscopy was used to characterize the catalytic process on the metal surface. Further, the characterization study of each catalyst was carried out. The selectivity was the highest over LiOH-doped Raney-Co (nearly 100 %) as the bi-molecular, surface condensation to N-butylidene-butylamine becomes negligible. The LiOH modification (i) quenches the Al 3+ Lewis acid sites that catalyze the condensation reaction (ii) reduces the catalyst sorption capacity for reactive species (iii) increases the probability of the step-wise hydrogenation via nitrene species. Further, in the presence of the strong nucleophile OH- the condensation reaction is hindered.

Download or read book Industrial Green Chemistry written by Serge Kaliaguine and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-12-07 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors and authors, with backgrounds in academia and industry, tie together recent and established technologies for the upcoming change to sustainable industrial chemistry. The extensive worldwide activities towards that goal are exemplified with a series of green processes. Some of these processes are already commercially applied (squalene to squalane, hydraulic fluids from vegetable oils, biosourced polycarbonates), others are ready for a large scale implementation (glycerol to acrylic acid, biosourced acrylonitrile and levulinic acid, polyamides from fatty nitriles-esters hydrogenation, butadiene from bioethanol) or are being developed (cyclic carbonates from epoxides, selective pyrolysis of biomass). This book is an indispensable source for the researchers and professionals who work for a greener chemical industry. The chapters have been arranged to guide students through the design of new processes for more sustainable chemistry, using case studies as examples.

Download or read book Heterogeneous Catalysis in Sustainable Synthesis written by Bela Torok and published by Elsevier. This book was released on 2021-09-17 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous Catalysis in Sustainable Synthesis is a practical guide to the use of solid catalysts in synthetic chemistry that focuses on environmentally benign applications. Collating essential information on solid catalysts into a single volume, it reveals how the efficient use of heterogeneous catalysts in synthetic chemistry can support sustainable applications. Beginning with a review of the fundamentals of heterogeneous catalytic synthesis, the book then explores the basic concepts of heterogeneous catalytic reactions from adsorption to catalyst poisons, the use of non-traditional activation methods, recommended solvents, the major types of both metal and non-metal solid catalysts, and applications of these catalysts in sustainable synthesis. Based on the extensive experience of its expert author, this book aims to encourage and support synthetic chemists in using solid catalysts in their own work, while also highlighting the important link between heterogeneous catalysis and sustainability to all those interested. Combines foundational knowledge with a focus on practical applications Organizes information by reaction type, allowing readers to easily find examples of how to carry out specific reaction types with solid catalysts Highlights emerging areas such as nanoparticle catalysis and metal-organic framework (MOF) based catalysts

Book Synopsis Applications of Hydrogenation and Dehydrogenation on Noble Metal Catalysts by : Bo Wang
Download or read book Applications of Hydrogenation and Dehydrogenation on Noble Metal Catalysts written by Bo Wang and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogenation and dehydrogenation on Pd- and Pt- catalysts are encountered in many industrial hydrocarbon processes. The present work considers the development of catalysts and their kinetic modeling along a general and rigorous approach. The first part deals with the kinetics of selective hydrogenation, more particularly of the C3 cut of a thermal cracking unit for olefins production. The kinetics of the gas phase selective hydrogenation of methyl-acetylene (MA) and propadiene (PD) over a Pd/y-alumina catalyst were investigated in a fixed bed tubular reactor at temperatures 60 - 80 oC and a pressure of 20 bara. Hougen-Watson type kinetic equations were derived. The formation of higher oligomers slowly deactivated the catalyst. The effect of the deactivating agent on the rates of the main reactions as well as on the deactivating agent formation itself was expressed in terms of a deactivation function multiplying the corresponding rates at zero deactivation. Then, the kinetic model was plugged into the reactor model to simulate an industrial adiabatic reactor. In the second part the production of hydrogen from hydrocarbons was investigated. In both cyclohexane and decalin dehydrogenations, conversions higher than 98% could be obtained over Pd/y-alumina catalyst at temperature of 320 and 340 oC, respectively, with no apparent deactivation for 30 h and with co-feed of H2 in the feed. Except for H2 and trace amounts of side cracking products, less than 0.01%, benzene was the only dehydrogenated product in cyclohexane dehydrogenation. In the case of decalin dehydrogenation, partially dehydrogenated product, tetralin, was also formed with selectivity lower than 5%, depending on operating conditions. A rigorous Hougen-Watson type kinetic model was derived, which accounted for both the dehydrogenation of cis- and trans- decalin in the feed and also the isomerization of the two isomers. Jet A is the logic fuel in the battlefields. The dehydrogenation of Jet A can produce H2 for military fuel cell application. Although the H2 production is lower than that of steam/autothermal reforming, it eliminates the needs of high temperature and product separation operation.
