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.

This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characteristics and catalytic properties of solvothermal derived ZnAI [subscritp 2]O[subscript 4] supported palladium catalysts were investigated and compared in terms of catalytic activities for liquid-phase hydrogenation of 1-hetyne, 1-heptene selectivities and catalyst deactivation to those of solvothermal derived AI[subscript 2]O[subscript3] and ZnO supported Pd catalysts. It was found that the solvothermal derived ZnAI[subscript 2]O[subscript 3], ZnO formed single crystallite. The palladium catalysts supported on solvothermal derived ZnAI[subscript 2]O[subscript 4] and ZnAI[subscript 2]O[subscript 3] calcined at higher temperature exhibited better performances than those supported on the supports calcined at lower temperatures. Moreover, it was found that Pd catalyst support on solvothermal-derived alpha alumina exhibited the higher activity than those supported on commercial one. For catalyst deactivation, Pd catalysts on the supports calcined at high temperature showed lower amount of Pd leaching.

This book was released on 2013 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological oils are potential sources of liquid transportation fuels. In the presence of a precious metal catalyst under reducing conditions, the transformation of biological oils to liquid fuels proceeds sequentially. First, any double bond is quickly saturated. The double bond saturation is followed by the hydrogenolysis of the ester linkages which releases the saturated fatty acids from the propane backbone. The fatty acids are then deoxygenated producing n-alkanes. Typically, the n-alkanes are further treated to meet the required physical properties of a particular fuel fraction. Although important, the deoxygenation of the fatty acid had not yet been studied in production-like conditions. For this reason, in this study, a comprehensive investigation of the deoxygenation of a representative fatty acid was carried out by studying stearic acid (S.A.) diluted in a highly isomerized C24 solvent. The deoxygenation of stearic acid was studied in the presence of hydrogen, in a trickle-bed reactor by using a 3 wt % carbon-supported palladium catalyst. In order to simplify the study of the kinetics of the S.A. deoxygenation, a uniform S.A. concentration across the catalyst bed was desired. For this reason, the entire study was conducted under differential conditions, by limiting the S.A. conversion to 10 percent. The limited conversion allowed me to assume uniform S.A. concentration across the catalyst bed. The liquid products were identified early on as n-heptadecane, n-octadecane, and stearyl stearate. The rate of formation for each liquid product was examined over wide-ranging sets of temperature, initial S.A. concentration and hydrogen pressure. Kinetic data for the different products were graphically derived and rate expressions were developed and presented. The S.A. deoxygenation reaction network in the presence of hydrogen was found to be rather complex. The observed rate of n-heptadecane production was a combined rate of two reactions, the stearic acid decarboxylation and the octadecanal decarbonylation. Likewise, the observed rate of n-octadecane production was the sum of the rates of octadecanol reduction and stearyl stearate hydrogenolysis. In order to estimate the contribution of each of the rates of S.A. decarboxylation and octadecanal decarbonylation to the total rate of n-heptadecane production, the relative rate of CO/CO2 production was studied over a range of temperature and hydrogen pressure. And, in order to estimate the contribution of the rate of alcohol reduction and the rate of stearyl stearate hydrogenolysis to the total observed rate of n-octadecane production, a complete study of palmityl stearate hydrogenolysis was carried out to estimate the stearyl stearate hydrogenolysis partial contribution to the overall rate of n-octadecane production.
Book Synopsis Comprehensive Inorganic Chemistry II by :
Download or read book Comprehensive Inorganic Chemistry II written by and published by Newnes. This book was released on 2013-07-23 with total page 7694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
