Book excerpt: Phenol, ethylbenzene, diphenylether, diphenylmethane, dibenzothiophene and carbazole are difficult to reduce under carbon monoxide-water conditions at 425°C in batch autoclaves. These conditions readily convert benzophenone, diphenylsulfide, thioanisole, phenylbenzyl ether, benzhydrol, quinoline, anthracene and 1,2-diphenylethane into a variety of products. For 1,2-diphenylethane, benzophenone, quinoline and benzylphenyl ether, the presence of tetralin had no effect on conversions; it had a negative effect on the conversions of thioanisole, diphenylsulfide and n-decanol; and a positive one on the anthracene reduction. Sodium carbonate aids the CO--H2O conversions of n-decanol, benzophenone and quinoline, has no effect on the reductions of 1,2-diphenylethane and anthracene and a negative effect on the thioanisole and diphenylsulfide runs. Iron oxide aided the conversions of the benzophenone and quinoline reductions, and ferrous sulfide favored the conversion of the quinoline and the thioanisole reduction, but it had no effect on the 1,2-diphenylethane and benzylphenyl ether runs and a negative effect on the diphenylsulfide, n-decanol and anthracene ones. For all but the quinoline reaction, where hydrogen was superior, a blend of carbon monoxide-water and hydrogen was the optimum set of reducing gases. Carbon monoxide and water outperformed hydrogen for the benzophenone and benzhydrol reductions. Three reports have been entered individually into EDB and ERA.

Download or read book Chemistry of Coal Conversion written by Richard H. Schlosberg and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 340 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, specialists from a variety of disciplines address the vast and complex subject of the chemistry of coal. The book comprises two parts: the first consists of seven review articles on coal chemistry, including NMR, tandem mass spectrometry, physics, liquefaction, catalytic reactions, devolatilization and combustion. Of particular interest in this part, is the frequent inclusion in many of the contributions of the authors' own research results, hitherto unpublished elsewhere. Good examples of this are the work on magnetic susceptibility of coal (a new branch of coal physics) and the article on tandem mass spectrometry (a new branch of analytical chemistry of coal). The second part contains twelve original articles covering characterization and chemistry of coal, structure and depolymerization, analytical methods including gas chromatography, mass spectrometry, gas-liquid chromatography, size-exclusion chromatography and analysis of oxygen by fast-neutron activation. Physical chemistry and physical properties of coal are dealt with in articles on coal slurry electrolysis, oxidation, thermal decomposition, absorption and diffusion.
