Available in PDF, EPUB and Kindle. Book excerpt: A new approach is described to observe, in real time and under realistic environments, the molecular processes of both primary and secondary pyrolysis of carbonaceous solids. The method employs the burnt-gas region of one-atmosphere H2-O2-Ar flames as the pyrolysis medium and permits the observation of the evolved vapor by direct, free-jet, molecular-beam mass spectrometry. The features of the sampling system are described and the phenomena accompanying sampling are discussed. Performance of the flame-pyrolysis and sampling system is documented. Applications are also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Initial, qualitative results for the primary and secondary pyrolysis of biomass and related compounds are shown, using the flame-pyrolysis, direct free-jet, molecular-beam, mass-spectrometric sampling system described in the companion paper (Part I). Time resolved pyrolysis data are shown for wood. Integrated primary pyrolysis spectra are shown for cellulose, lignin, wood, oil shale, coal, and polyethylene specimens, flash-heated in one-atmosphere, 900 degrees C steam-argon. Our spectra for cellulose and lignin are compared with several reported in the literature using analytical pyrolysis and other techniques. Secondary cracking spectra of ethane, n-butane and cellulose are shown illustrating the ability of this technique to separate primary from secondary processes. Finally, the present technique is compared with more conventional analytical pyrolysis mass spectrometry approaches.

Book Synopsis Analytical Pyrolysis by : Kent J Voorhees
Download or read book Analytical Pyrolysis written by Kent J Voorhees and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical Pyrolysis: Techniques and Applications provides an overview of analytical pyrolysis applied to geochemistry, biology, polymers, and biomass. This book presents a survey of basic phenomena, data analysis, and instrumentation. Organized into 15 chapters, this book begins with an overview of mass spectrometry in developing ion sources that are applicable to materials that either have low volatility, high molecular weight, are thermally unstable or some combination of the three. This text then examines the role of thermal processes in many of the desorption methods. Other chapters consider desorption techniques, which are closely allied to analytical pyrolysis. This book discusses as well the Flash Vacuum Pyrolysis/Field Ionization Mass Spectrometry (FVP/FIMS) technique, which is based on a direct link between the pyrolysis unit and a double focusing mass spectrometer. The final chapter deals with inert atmosphere poly (vinyl chloride) (PVC) thermal decomposition. This book is a valuable resource for chemists and researchers.

Book Synopsis Analytical Pyrolysis by : Peter Kusch
Download or read book Analytical Pyrolysis written by Peter Kusch and published by BoD – Books on Demand. This book was released on 2019-02-13 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical pyrolysis deals with the structural identification and quantitation of pyrolysis products with the ultimate aim of establishing the identity of the original material and the mechanisms of its thermal decomposition. The pyrolytic process is carried out in a pyrolyzer interfaced with analytical instrumentation such as gas chromatography (GC), mass spectrometry (MS), gas chromatography coupled with mass spectrometry (GC/MS), or with Fourier-transform infrared spectroscopy (GC/FTIR). By measurement and identification of pyrolysis products, the molecular composition of the original sample can often be reconstructed.This book is the outcome of contributions by experts in the field of pyrolysis and includes applications of the analytical pyrolysis-GC/MS to characterize the structure of synthetic organic polymers and lignocellulosic materials as well as cellulosic pulps and isolated lignins, solid wood, waste particle board, and bio-oil. The thermal degradation of cellulose and biomass is examined by scanning electron micrography, FTIR spectroscopy, thermogravimetry (TG), differential thermal analysis, and TG/MS. The calorimetric determination of high heating values of different raw biomass, plastic waste, and biomass/plastic waste mixtures and their by-products resulting from pyrolysis is described.

Book excerpt: This report summarizes the direct mass spectrometric studies of fast pyrolysis completed in FY 1981, with detailed results of fourth-quarter activities. The latest version of the flame gas pyrolysis/molecular-beam sampling system is schematized with discussion of fast data acquisition capabilities and instrument tuning. Temperature effects in the pyrolysis plume are presented. Background-corrected mass spectra are shown for the pyrolysis in 900°C steam-argon of small samples (~10-20 mg) of levoglucosan, glucose, cellulose, lignin, and wood. A very preliminary identification of major producs and comparison with the literature is presented. The effects of physical dimensions and alkali catalysts on primary pyrolysis products are shown. A grid-heating apparatus is described, and plans for FY 1982 are outlined.
Book Synopsis Molecular Beam Sampling Mass Spectrometry of High Heating Rate Pyrolysis: Description of Data Acquisition System and Pyrolysis of HMX in a Polyurethane Binder by : Richard A. Beyer
Download or read book Molecular Beam Sampling Mass Spectrometry of High Heating Rate Pyrolysis: Description of Data Acquisition System and Pyrolysis of HMX in a Polyurethane Binder written by Richard A. Beyer and published by . This book was released on 1978 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The data acquisition capability of the time-of-flight mass spectrometer used with the molecular beam sampling system has been expanded. An oscilloscope intensity-modulated raster technique using negative film scanned by a microdensitometer provides simultaneous semi-quantitative time-resolved mass spectra of all masses up to 160 amu with time resolution down to 10 ms. A system of parallel sample/hold channels which follow predetermined masses with time resolution near that of the spectrometer cycle time has been assembled and shown to have good dynamic range, adequate mass resolution, and provide good reproducibility. This system has been used to study the products of low pressure pyrolysis of nitrocellulose and cyclotetramethylene tetranitramine/polyurethane binder. Using a carbon dioxide laser for heating the samples up to 5000 deg/s heating rate effects are clearly demonstrated for NC but are not observed for HMX/PU. Relative amounts of the major decomposition species observed for the HMX/PU were nitrous oxide, 100; nitrogen dioxide, 54; hydrogen cyanide, 42; formaldehyde, 39; and nitric oxide, 27. The large amounts of nitrogen dioxide is compatible with the breaking of the N-N bond as the first step of the thermal decomposition of HMX. (Author).
