Available in PDF, EPUB and Kindle. Book excerpt: The different methods for enhancing the catalytic activity of transition metal complexes in hydrocarbon (particularly, alkylarene) oxidations with dioxygen are briefly discussed. The role played by H-bonds in mechanisms of homogeneous catalysis is also analysed. Furthermore, the authors propose a strategy of controlling the catalytic activity of Fe(II,III)(acac)nL2 complexes (L2 = R4NBr or 18C6) by adding H2O to small concentrations. In addition, the activity of Ni, Fe, and Co catalysts in microsteps of chain initiation (O2 activation), and propagation (Cat + RO2?) in the radical chain process of ethylbenzene oxidation is assessed by original method offered by authors. New concepts of mechanism of chain process of hydrocarbon oxidations with dioxygen, catalysed with transition metal complexes, participation of catalysts in microsteps of complicated hydrocarbon oxidation, activity M-O2 (M = Co, Ni, Fe) complexes in different oxidation reactions are briefly stated, and the self-assembled (self-organised) systems mediated by transition metals are briefly considered in connection with increasing research interest in chemical transformations with use of these systems.

This book was released on 2012-12-06 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective Oxidation by Heterogeneous Catalysis covers one of the major areas of industrial petrochemical production, outlining open questions and new opportunities. It gives keys for the interpretation and analysis of data and design of new catalysts and reactions, and provides guidelines for future research. A distinctive feature of this book is the use of concept by example. Rather than reporting an overview of the literature results, the authors have selected some representative examples, the in-depth analysis of which makes it possible to clarify the fundamental, but new concepts necessary for a better understanding of the new opportunities in this field and the design of new catalysts or catalytic reactions. Attention is given not only to the catalyst itself, but also to the use of the catalyst inside the process, thus evidencing the relationship between catalyst design and engineering aspects of the process. This book provides suggestions for new innovative directions of research and indications on how to reconsider the field of selective oxidation from different perspectives, outlining that is not a mature field of research, but that new important breakthroughs can be derived from fundamental and applied research. Suggestions are offered on how to use less conventional approaches in terms of both catalyst design and analysis of the data.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The integrated LNT/SCR system is a promising technology for the reduction of NOx emission from the exhaust of lean-burn or diesel engine vehicles. The LNT/SCR operating concept involves the storage of NOx during the lean phase while unreacted hydrocarbons (C3H6, C2H4 etc.) and generated NH3 exit the LNT during the rich phase. In addition to NH3, olefinic hydrocarbons and/or partially oxidized species that break through the LNT may also adsorb on the SCR catalyst leading to additional NOx reduction by those species. In first part of the work, we performed bench-flow reactor and in-situ DRIFTS experiments to elucidate the propylene + NO + O2 reaction system on Cu-SSZ13 (chabazite) monolithic catalyst. Experiments were conducted under both steady state and transient conditions for application relevant feed conditions. Based on the bench-flow reactor studies and in-situ DRIFTS experiments a phenomenological reaction mechanism is proposed that involves reaction between oxygenates (partially oxidized hydrocarbon species) and NO to form isocyanates species ( -NCO), detected by DRIFTS which are further reduced to N2. The experimental work is followed by developing a mechanistic-based kinetic model is developed for selective catalytic reduction of NO with C3H6 on Cu chabazite (Cu-SSZ13) monolithic catalyst based on bench scale flow reactor studies and in-situ DRIFTS measurements. The kinetic model was developed in steps, starting with steady-state CO oxidation, followed by C3H6 oxidation, and then the C3H6 + NO + O2 reaction system. The models for CO+O2, C3H6+O2 and C3H6+NO+O2 were also validated using a new set of steady state experiments. The model provides insight about non-NH3 pathways (hydrocarbons, oxygenates, isocyanates etc.) for NOx reduction across the SCR. Finally, we developed a global kinetic model for co oxidation of CO and C3H6 over Pt/Al2O3 monolithic catalyst. The kinetic model developed is used to elucidate the dynamic and steady state hysteresis behavior observed during oxidation of CO+C3H6 mixture on Pt/Al2O3.

This book was released on 2000-03-31 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the climate change discussion, non-CO2 greenhouse gases (NCGGs) received official political recognition for the first time in 1997, when agreement was reached on the Kyoto Protocol. As a result methane, nitrous oxide, HFCs, PFCs and SF6 now provide attractive options for detailing the national targets for the reduction of greenhouse gas emissions meant to control climate change. This book is the second volume in this area and addresses three main topics. Firstly, it documents progress with respect to our knowledge of the sources and sinks of NCGGs. Information on this subject is essential in order to reduce the uncertainties in national emissions inventories which serve as the reference values for commitments of countries in the framework of the Kyoto Protocol. Secondly, this volume deals with the control options for the NCGGs and contains a wealth of information in this area. Emerging technologies here provide business opportunities, in particular in connection with the flexible mechanisms for mitigation projects in developing countries which have been agreed in Kyoto. Thirdly, the book treats the policy implementation of mitigation options for greenhouse gas emissions. Tools for control policies, both on the national and international level, and for different sectors of industry are discussed. National integrated approaches, including the ones from the United States Environmental Protection Agency and the Netherlands Ministry of Environment which both sponsored the conference, provide guidance for defining the most effective greenhouse gases mitigation plans in different situations. This volume is being published in support of the IPCC Process and will serve as a reference for IPCC's Third Assessment Report.

Available in PDF, EPUB and Kindle. Book excerpt: As in the study of transition metal complexes in solution, molecular spectroscopic methods - principally the infrared, ultraviolet/visible and electron spin resonance spectroscopies - have played key roles in establishing the concepts of coordination chemistry occurring at the surfaces of solids. This book describes the development of the principals of coordination chemistry of oxide surfaces using analyses of data obtained by these methods. The nature, properties, concentration of the surface adsorption centers and their influence on the character of interaction with different molecules are investigated. The book commences with an account of the basic theoretical principles and experimental techniques of the various spectroscopy methods, with special attention devoted to in situ measurements where the oxide or catalyst sample is in contact with the adsorbate or the reactant. A detailed account is presented of the methods for characterizing the oxidation state and degree of coordination of surface cations and oxygen anions by the adsorption of probe molecules. The complexation of many inorganic, organometallic and organic molecules with different oxide systems is critically examined, and a classification of formed surface compounds, based on the interaction with definite type of adsorption centers, is given. Possible mechanisms of numerous catalytic reactions, including the transformation of organic molecules over acidic catalysts via the carboionic mechanism, are discussed using the spectroscopic identifications of reaction intermediates. A comprehensive analysis of the literature on the interpretation of the spectra of surface compounds on oxides is presented. This highly illustrated and extensively referenced volume is intended for specialists working in the fields of surface physical chemistry, surface and materials sciences, and adsorption phenomena and is essential reading for those involved in the heterogeneous catalysis by transition metal-oxides.
