This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over one quarter of the energy usage in the United States currently occurs in the transportation sector. Improvements in energy conversion efficiency and sustainability in transportation applications, therefore, can substantially contribute to improved energy security in our future. The design of advanced high-efficiency energy conversion devices for transportation applications can be facilitated with complex computer models of combustion processes. The development of these models requires a large experimental database to ensure accuracy of the computational predictions. This thesis discusses how experimental studies are utilized to create a database of rate constants for elementary reactions; these rate constants are integral components of any computational model of combustion chemistry. During a combustion process, the reaction of the hydroxyl (OH) radical, a highly reactive chemical intermediate, with a combustible fuel molecule is a major fuel consumption pathway under many combustion conditions. Thus, the rate constants for these types of reactions must be accurately known to develop a computational model that correctly describes the combustion chemistry. This thesis presents an experimental method for measuring rate constants in the reaction family of OH + Fuel -> Products using a shock tube reactor, laser diagnostics, and tert-butylhydroperoxide (TBHP) as an OH radical precursor. Important rate constant parameters describing subsequent reactions of TBHP decomposition are also studied. Current transportation fuels of interest in the combustion community include molecules in the alkane and butanol classes. Alkane molecules are a major component of many petroleum-derived fuels such as gasoline and jet fuel. Isomers of the butanol molecule are gaining popularity as a potential renewable alternative to gasoline because of their high energy density and the many known methods of production from biomass and agricultural byproducts. The rate constant measurement method is applied to the reaction of OH with three alkane molecules (n-pentane, n-heptane, and n-nonane) and four isomers of butanol (n-butanol, iso-butanol, sec-butanol, tert-butanol), and the results are reported in this thesis. Comparison of the rate constant results to estimation methods in the literature are presented, and, for several of the isomers of butanol studied, the measured data are also used to validate and/or suggest refinements to existing detailed kinetic mechanisms.

Download or read book Atmospheric Ozone Research and its Policy Implications written by S.D. Lee and published by Elsevier. This book was released on 1989-01-01 with total page 1067 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings describe the current state-of-the-art of ozone research. A wide range of topics is discussed including: emissions, transport and transformation of precursors of ozone and of ozone itself, the distribution of ozone, the deposition of ozone at the earth's surface, and its effects on man and the environment. Attention is also given to the role of stratospheric ozone and the role of the ultraviolet radiation which is transmitted through the ozone layer. Finally it describes in detail present and future policy measures to reduce the ozone in the lower atmosphere and to protect the ozone layer in the stratosphere.Many of the papers describe recent developments and new research results. Research carried out in both in Europe and in the United States is described, as are the policy measures which are being taken by both European and U.S. governments.

Download or read book The Hydroxyl Radical Reaction Rate Constant and Products of Dimethyl Succinate written by and published by . This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relative rate technique has been used to examine the kinetics for the reaction of the hydroxyl radical (OH) with dimethyl succinate (DMS, CH3OC(=O)CH2CH2C(=O)OCH3). The measured rate constant for OH + DMS was 1.5 +/- 0.4 x 10(exp -12) cc/molecule/s at 297 +/- 3 deg K and 1 atmosphere total pressure. This is in agreement with the predicted value of 1.15 x 10(exp -12) cc/molecule/s determined by structure activity relationships. To more clearly define DMS's atmospheric degradation mechanism, the products of the OH + DMS reaction were also investigated. The only primary product detected was mono methyl succinate (MMS, CH3OC(=O)CH2CH2C(=O)OH)) at a yield of only 2.17 +/- 0.25%. Extensive efforts were used to identify other primary products but none were measured. Formic acid (HC(=O)OH); however, was observed as a secondary product being formed at a rate of (4.6 +/- 1.3) x 10(exp 14) molecules/second, 60 minutes after initiating the OH + DMS reaction. Formic acid is believed to be a degradation product of the primary product, methyl glyoxylate (MG, CH3OC(=O)C(=O)H). Product formation pathways are discussed in light of current understanding of the atmospheric chemistry of oxygenated organic compounds.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The goal of this study was to investigate some of the fundamental chemistry of the reactions between the hydroxyl radical and apply this knowledge to the treatment of chemical contaminants in real world waters. To accomplish this goal, the techniques of electron pulse radiolysis were used to quantify second-order rate constants for the reaction between the HO· radical and well characterized OM samples. Studies of HO· radical reactivity with model polyethylene glycol polymers were performed to help understand OM-HO· reactivity. Experiments using steady state radiolysis were performed in order to assess the effect of long-term, seasonal variability in OM composition on the degradation of probe compounds used as model chemical contaminants. In addition, the photochemical production of HO· from OM sensitization was also investigated.
