This book was released on 2017-01-05 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis offers novel methods for catalyst and process design for the selective hydrogenation of acetylene and 1,3-butadiene. The author predicts the properties of supported Pd–Ni bimetallic catalysts using density functional theory (DFT) calculations and temperature-programmed desorption (TPD). The excellent correlation between model surfaces and supported catalysts demonstrates the feasibility of designing effective bimetallic catalysts for selective hydrogenation reactions. The author also proposes a method for designing non-precious metal catalysts to replace precious metals. She modifies the process of selective hydrogenation of acetylene by coupling the selective adsorption to the selective hydrogenation in the liquid phase, as a result of which the ethylene selectivity is greatly improved and heat transfer is greatly enhanced. Lastly, by analyzing the mechanism of liquid-phase hydrogenation, the author proposes a multi-stage slurry bed reactor for industrial applications.“/p>

Book Synopsis Correlating Electronic and Catalytic Properties of Bimetallic Surfaces for Model Hydrogenation Reactions by : Amit Goda
Download or read book Correlating Electronic and Catalytic Properties of Bimetallic Surfaces for Model Hydrogenation Reactions written by Amit Goda and published by ProQuest. This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of bimetallic surfaces leads to a change in the electronic properties of the parent metal surface, which results in changes in chemical reactivity. The activity and selectivity of reactions on transition metal surfaces can be increased by creation of such bimetallic combinations. In this dissertation, the correlation of electronic properties of bimetallic surfaces with the reaction pathways of C 2 hydrocarbons, catalytic properties of higher alkenes and selective reduction of acetic acid to acetaldehyde is illustrated. For the study on C 2 hydrocarbons, Density Functional Theory (DFT) was used to study the binding of hydrogen, ethylene, acetylene, ethyl and vinyl on monometallic and bimetallic transition metal surfaces. The binding energies (B.E.) of these species were found to correlate with the d-band centers of the surfaces. DFT-calculated B.E. and BOC-calculated activation barrier values were used to calculate the selectivity for acetylene hydrogenation vs. ethylene hydrogenation. The results showed that for monometallic fcc(111) surfaces, the selectivity for acetylene hydrogenation followed the trend Ni> Pt> Pd. In addition, the general trend in the binding energy of other alkenes, including butene, pentane, hexene, and cyclohexene also followed similar binding energy trend as compared to ethylene. Adsorption studies were also carried out for benzene in two favorable configurations. Along with the adsorption trends, DFT based studies were carried out to study the effect of hydrocarbon chain length and cyclization on the adsorption on Pt-based bimetallic surfaces. In the case of selective reduction of acetic acid, DFT calculations were used to study the modes and energies of adsorption of the involved intermediates along with the overall reaction energies for the elementary steps. DFT calculations on acetic acid, acetaldehyde and ethanol showed that the binding energy (B.E.) of the molecules decreases as the surface d-band center shifts away from the Fermi level. It was observed that ethanol binds more strongly than acetaldehyde on Pt(111) as well as the subsurface Ni on Pt (Pt-Ni-Pt) surface, but the trend reverses when Ni is on top of Pt (Ni-Pt-Pt). This change in B.E. affects the overall heat of reaction for ethoxy going to ethanol, making it highly exothermic on Pt(111) and Pt-Ni-Pt surfaces, while it is endothermic on the Ni-Pt- Pt surface. These changes in the thermodynamics of reactions should affect the rate determining steps toward selective acetaldehyde formation, which was determined by calculating the activation barriers for the elementary steps.

This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the oil embargo, in the winter 1973174, parts of Western Europe present ed an almost war-like aspect on Saturdays and Sundays: no traffic on the high ways, no crowds at ski resorts and other weekend entertainment places, no gaso line at the pumps. Living and teaching then in that part of the world, and discussing the situa tion with our students, we came to the conclusion that it would be timely to col lect the fine chemistry already known at the time in the field of conversion of coal to gasoline and other chemicals, and by this way help to draw the attention to this important alternative to crude oil. The idea of this book was born. The energy shock of the early seventies has been healthy and of great conse quences in chemistry. Large amounts of research money have been put to work since, and our knowledge of the possibilities and limitations of coal-based chemistry has increased enormously. During several years it appeared inap propriate to write a monograph about a topic which was in the midst of such an impetuous development. Nevertheless, we collected, and critically selected, the upcoming work as it appeared in the literature, and also tried to provide some modest input ourselves. Now, ten years later, the situation seems to be settled to a certain degree.

Book Synopsis Oxygenates by Homologation or CO Hydrogenation with Metal Complexes by : A. Braca

This book was released on 1993-12-31 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Born and initially developed in various industrial laboratories, mainly in U.S.A. and Gennany, homogeneous phase catalytic carbon monoxide hydrogenation and alcohols and their derivatives carbonylation and homologation, have generally been considered and reviewed separately in the course of their 40 years history without concern for common aspects in the chemical transfonnations and in catalysis. Thanks to researchers of Japanese companies participating in the National C 1 Chemistry Project (1980-1987) the scientific and technical approaches in this field have been unified and applied in parallel, in the light of some common aspects of the chemical reactions and mechanisms. Now, at a moment when research seems becahned, a general presentation and discussion of the most recent topics might be an useful basis for further development of this chemistry. To delimit and simplify the discussion of the chemical aspects and the nature of the catalysts involved, the present review is limited to reactions employing homogeneous metal complexes for the direct conversion of syngas to oxygenates and to the hydrocarbonylation of these last to homologous derivatives. Since the previous practically contemporary reviews by Dombek [in Adv. Organomet. Chern. (1983)] on CO hydrogenation and by the present authors [in Asp.Homog.Catal.(Reidel Pu.l984)] on alcohol homologation fully cover the literature up to 1982, here we mainly refer to work done after 1982, and consider the cited reviews as covering the historical development of research in the 1940- 1980 period.
Book Synopsis Primer in Frustrated Lewis Pair Hydrogenation by : Douglas Stephan
Download or read book Primer in Frustrated Lewis Pair Hydrogenation written by Douglas Stephan and published by Royal Society of Chemistry. This book was released on 2021-11-17 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for senior undergraduate and graduate students, as well as those chemists unfamiliar with “frustrated Lewis pairs (FLPs)”, this text serves as an introduction to the both the concept and application of FLPs in hydrogenation catalysis. The book begins by setting the stage as it was around the turn of the century. While the dramatic impacts of catalysis were undeniable, there was dependence of such technologies on transition metal chemistry. Contrastingly, the chemistry of main group elements was dominated by Lewis acid-base behavior. However, these perceptions were altered with the discovery of the ability of “frustrated Lewis pairs (FLPs)” to activate dihydrogen. The basic features, and mechanisms of action of these unique main group systems are chronicled, while the evolution of the initial findings to applications in catalytic hydrogenation is discussed. A subsequent chapter focuses on the breadth of organic substrates for which borane based FLP hydrogenations are effective. This is furthered with a chapter on the metal-free enantioselective reductions. FLP chemistry is not limited to systems involving boranes and this book also catalogues a range of FLP hydrogenation catalysts involving elements from across the periodic table. The final chapter in the book describes other directions of interest where the application of the concept of FLPs hydrogenation are beginning to emerge. Ideal for course use and self study, this book provides synthetic chemists with a fresh, expert introduction to the field. The reader will be left recognizing that hydrogenation catalysts is a domain no longer limited to transition metals.

Download or read book Homogeneous Hydrogenation written by P.A. Chaloner and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homogeneous hydrogenation is one of the most thoroughly studied fields of homogeneous catalysis. The results of these studies have proved to be most important for an understanding of the underlying principles of the activation of small molecules by transition metal complexes. During the past three decades homogeneous hydrogenation has found widespread application in organic chemistry, including the production of important pharmaceuticals, especially where a sophisticated degree of selectivity is required. This volume presents a general account of the main principles and applications of homogeneous hydrogenation by transition metal complexes. Special attention is devoted to the mechanisms by which these processes occur, and the role of the recently discovered complexes of molecular hydrogen is described. Sources of hydrogen, other than H2, are also considered (transfer hydrogenation). The latest achievements in highly stereoselective hydrogenations have made possible many new applications in organic synthesis. These applications are documented by giving details of the reduction of important unsaturated substrates (alkenes, alkynes, aldehydes and ketones, nitrocompounds, etc.). Hydrogenation in biphasic and phase transfer catalyzed systems is also described. Finally, a discussion of the biochemical routes of H2 activation highlights the similarities and differences in performing hydrogenation in both natural and synthetic systems. For researchers working in the fields of homogeneous catalysis, especially in areas such as pharmaceuticals, plastics and fine chemicals.
