This book was released on 1992 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of this work are to provide accurate data on the temperature dependence of the kinetics of elementary combustion reactions (i) for use by combustion modelers, and (ii) to gain a better fundamental understanding of, and hence predictive ability for, the chemistry involved. Experimental measurements are made using the pseudo-static HTP (high-temperature photochemistry) technique. This approach allows observations on single reactions in the 300 to 1800 K temperature range to be made. Typical total (bath gas) pressures are in the 100 to 1000 mbar range. Ground-state O and H atoms are produced by flash or excimer laser photolysis of suitable precursors (O2, CO2, SO2, NH3). The relative atom concentrations are monitored by resonance fluorescence pumped by a cw microwave discharge flow lamp. The molecular reactant-in-excess is introduced through a cooled inlet. Adequate time for mixing, 0.1 to 10 s, between this inlet and the photolysis/observation zone is achieved by using slow flows (typically less than 20 cm s−1). Results are reported for: O-Atom Reactions with the Four Isomeric Butenes, H + HCl --> H2 + Cl, and the O-atom 1,3-butadiene reaction.

This book was released on 1976 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper understanding, prediction and modeling of combustion systems requires reliable knowledge of the reaction mechanisms and rate coefficients of individual elementary reactions as a function of temperature. This review discusses a unique experimental method for providing such data. This HTFFR method has been used over the 300-1700 K range and is suitable for temperatures up to approx. 2000 K. The reaction Al + CO2 + Al0 + CO is discussed in some detail to illustrate the method, which has thus far been applied to reactions of metal atoms and metal monoxides. A summary of the rate coefficient data obtained in HTFFRs is given and prospects for extensions of the technique to other types of combustion reactions are discussed. (Author).

Download or read book Global Chemical Kinetics of Fossil Fuels written by Alan K. Burnham and published by Springer. This book was released on 2017-02-11 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the origin and chemical structure of sedimentary organic matter, how that structure relates to appropriate chemical reaction models, how to obtain reaction data uncontaminated by heat and mass transfer, and how to convert that data into global kinetic models that extrapolate over wide temperature ranges. It also shows applications for in-situ and above-ground processing of oil shale, coal and other heavy fossil fuels. It is essential reading for anyone who wants to develop and apply reliable chemical kinetic models for natural petroleum formation and fossil fuel processing and is designed for course use in petroleum systems modelling. Problem sets, examples and case studies are included to aid in teaching and learning. It presents original work and contains an extensive reanalysis of data from the literature.

Download or read book Wide Temperature Range Kinetics of Elementary Combustion Reactions for Army Models written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of this program are to provide accurate kinetic data on isolated elementary reactions at temperatures relevant to Army combustion models, particularly for propellant combustion dark zones and also for development of halon replacements for fire retardation. Measurements have been made in high temperature photochemistry (HTP) reactors. Rate coefficient expressions over wide temperature ranges are reported for the reactions O+N2O -> O2+N2,N + N2O ->N2 + NO, O +CHF3 ->OH + CF3, H + NO + Ar -> HNO + Ar, NH + CO2 ->HNO +CO. For the first of these reactions the relation to the alternate 2NO product channel is discussed. The potential impact of the results on the continuing development of Army models is considered. A statistical method has been developed for testing the exponentiality of noisy measurements in the time domain, such as are sometimes obtained in HTP and many other types of experiments.
