Download or read book NMR for Liquid Fossil Fuels written by L. Petrakis and published by Elsevier. This book was released on 2012-12-02 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution nuclear magnetic resonance (NMR) of liquid fuels has provided valuable information on the molecular structures present in these fuels. The chemical insight gained through NMR studies has the potential to enhance significantly the development of processes for the utilization of fossil energy. For this potential to be fully realized, users of NMR information must be able to communicate effectively with NMR experts. Conversely, NMR experts must understand the type of information that users will attempt to derive from their spectra. The goal of this book is to strengthen the lines of communication between NMR experts and users in the area of NMR of liquid fuels.The book comprises two parts. The first part presents elements of relevant NMR phenomenology, including a definition of the most important NMR parameters, an introduction to Fourier transform NMR and a discussion of newer pulse techniques. Sufficient background material is presented to enable the reader to follow such techniques as spin echo, two-dimensional and polarization transfer experiments. These techniques are illustrated by extensive examples derived from fuel chemistry. The second part of the book addresses the interpretation of NMR spectra and is based, to a very large extent, on the work of the authors who have used NMR in a variety of applications in fossil fuels. This part describes in detail the three basic methods for interpreting NMR spectra of liquid fuels: average structural parameter calculations, average molecule construction and functional group analysis. The use of NMR in engineering calculations is also presented and should be particularly useful to those interested in processing of fossil fuels. Extensive examples are drawn from petroleum, shale oils, coal liquids and model systems. Computer programs for performing the characterizations from the spectra are provided.The book will appeal to a wide range of professionals. With its emphasis on applications, it will be of particular interest to those who use NMR to characterize liquid fossil fuels or those who provide NMR assistance to fossil fuel scientists and technologists.

Download or read book Atomic and Nuclear Methods in Fossil Energy Research written by Filby and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased demand on fossil fuels for energy production has resulted in expanded research and development efforts on direct use of fossil fuels and conversion of fossil fuels into synthetic fuels. These efforts have focused on the efficiency of the energy production and/or conversion processes, and of the emission control technology, as well as delineation of the health and environmental impacts of those processes and their by-products. A key ingredient of these studies is the analytical capability necessary to identify and quan tify those chemicals of interest in the process and by-produce streams from coal combustion, oil shale retorting, petroleum refin ing, coal l1quifaction and gasification. These capabilities are needed to analyze a formidable range of materials including liquids, solids, gases and aerosols containing large numbers of criteria and pollutants including potentially hazardous polynuclear aromatic hy drocarbons, organo-sulfur and organo-nitrogen species, trace elements and heavy metals, among others. Taking notice of these developments we sought to provide a forum to discuss the latest information on new and novel applica tions of a subset of those necessary analytical capabilities, namely atomic and nuclear techniques. Consequently, we organized the con ference on Atomic and Nuclear Methods in Fossil Fuel Energy Research, which was held in Mayaguez, Puerto Rico from December 1 to December 4, 1980."

Download or read book Asphaltenes and Asphalts 2 written by T.F. Yen and published by Elsevier. This book was released on 2000-08-16 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume in the series of Asphaltenes and Asphalts. Since the publication of the first volume in 1994, there has been a significant advancement in our knowledge. Knowledge of both asphaltenes and asphalts is needed by several disciplines, and often the progress is dictated by interdisciplinary sciences and technology. This includes material sciences, fuel sciences, chemical engineering, civil engineering, environmental engineering, polymer sciences, transportation engineering, petroleum engineering, chemistry, geological sciences, physics, geochemistry rheology, biological sciences, tribology, soil sciences, petroleum science. The development in this field is not based on our knowledge of chemistry or petroleum engineering alone, as many chemists and petroleum engineers believe. In this volume, therefore, significant contributions from different disciplines have been included.

Download or read book Compact NMR written by Bernhard Blümich and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-08-22 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide an introduction to the practical use of mobile NMR at a level as basic as the operation of a smart phone. Each description follows the same didactic pattern: introduction, basic theory, pulse sequences and parameters, beginners-level measurements, advanced-level measurements, and data processing. Nuclear Magnetic Resonance (NMR) spectroscopy is the most popular method for chemists to analyze molecular structures while Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool for medical doctors that provides high-contrast images of biological tissue depicting the brain function and the beating heart. In both applications large super-conducting magnets are employed which magnetize atomic nuclei of an object positioned inside the magnet. Their circulating motion is interrogated by radio-frequency waves. Depending on the operating mode, the frequency spectrum provides the chemist with molecular information, the medical doctor with anatomic images, while the materials scientist is interested in NMR relaxation parameters, which scale with material properties and determine the contrast in magnetic resonance images. Recent advances in magnet technology led to a variety of small permanent magnets, by which NMR spectra, images, and relaxation parameters can be measured with mobile and low-cost instruments.
