Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book is twofold. First, in response to the well documented oil shocks of the 1970s there arose a resurgence of research activity in the synthetic fuels area. This book attempts to capture some of the leading edge advances which have been made over the past decade in the area of the chemistry of coal conversion. The second driving force behind this book is to jog people's memories about the fundamental truths of the energy industry, i. e. , there IS a finite amount of liquid hydrocarbons on and under the earth's surface, most of the easy to find, produce, and use liquid hydrocarbons have been exploited, and the real need continues to be for liquid hydrocarbons for use as trans portation fuels. The uncertainty is not if synthetic liquids will be needed, but rat her when they will be needed. The inability to answer that question accurately caused many of the financial and research disruptions following the double shocks of the 1970s. Since future projections can only be based upon the historical record, they cannot anticipate major disruptions such as, e. g. , discovery of huge easily producible oils fields, or, on the other side, global or regional economic disruptions such as warfare. With this level of uncertainty, then, the second impetus is to point out how much research remains to be done at a time when fiscal support for fossil fuels research in the Uni ted States is rapidly spiraling downward.

Book excerpt: Coal Science, Volume 2 presents and evaluates the fundamental scientific areas involved with the structure, reactivity, and utilization of coal. This book reviews the coal's inorganic structure and reactivity and the role that ionic bonding plays in coal's chemical and physical structure and reactivity. Organized into four chapters, this volume begins with an overview of the area of mineral matter in coal and a critical survey of many specific aspects that are most intriguing scientifically. This text then examines the role of the solvent in the initial stage of coal liquefaction. Other chapters consider the primary products of decomposed plant matter, which are transformed into the various ranks of coals through a series of evolutionary changes. The final chapter deals with solvent extraction, which is the most commonly used methods for studying the chemical properties of coal. This book is a valuable resource for chemists, engineers, and research workers.

Download or read book The Effect of Selective Solvent Absorption on Coal Conversion. Final Technical Report written by and published by . This book was released on 1993 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a pair of different recycle oils from Wilsonville and 1H NMR, 13C NMR, gel permeation (GPC) chromatography, high pressure liquid chromatography (HPLC), and elemental analysis, no significant differences were observed between the composition of the recycle oil and that portion of the oil not absorbed by the coal. For these complex mixtures, coals are not selective absorbants. Since most of the heteroatoms responsible for most of the specific interactions have been removed by hydrogenolyses, this is perhaps not surprising. To address the issue of the role of hydrogen bond donors in the reused as hydrogen donor coal, tetralin and 2-t-butyltetralin were used as hydrogen donor solvents. This work is reported in detail in Section 2. The basic idea is that the presence of the t-butyl group on the aromatic ring will hinder or block diffusion of the hydrogen donor into the coal resulting in lower conversions and less hydrogen transferred with 2-t-butyltetralin than with tetralin. Observed was identical amounts of hydrogen transfer and nearly identical conversions to pyridine solubles for both hydrogen donors. Diffusion of hydrogen donors into the coal does not seem to play a significant role in coal conversion. Finally, in Section 3 is discussed the unfavorable impact on conversion of the structural rearrangements which occur when Illinois No. 6 coal is swollen with a solvent. We believe this rearrangement results in a more strongly associated solid leading to the diminution of coal reactions. Hydrogen donor diffusion does not seem to be a major factor in coal conversion while the structural rearrangement does. Both areas warrant further exploration.

Available in PDF, EPUB and Kindle. Book excerpt: Coal liquefaction experiments using a 400-lb/day bubble-column reactor tested the catalytic effects of added mineral matter level on coal conversion, desulfurization, and distillate yields in continuous operation under recycle conditions, with specific emphasis on the use of a disposable pyrite catalyst indigenous to the feed coal. Western Kentucky No. 11 run-of-mine (ROM) and washed coals were used as feedstocks to determine the effects of levels of mineral matter, specifically iron compounds. Liquefaction reactivity as characterized by total distillate yield was lower for washed coal, which contained less mineral matter. Liquefaction reactivity was regained when pyrite concentrate was added as a disposable catalyst to the washed coal feed in sufficient quantity to match the feed iron concentration of the run-of-mine coal liquefaction test run.
