This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive research program was conducted to ascertain ways to improve oil yields and process economics of direct coal liquefaction. The effects of removing heteroatoms from the solvent, pretreating coal by several techniques (including solvent extraction, oxidation, grinding, and ion exchange), and beneficiating coal by removing mineral species were investigated in both catalytic and noncatalytic coal liquefaction reactions. Additionally, fundamental studies were carried out to explain the role of heteroatoms in catalytic coal liquefaction. The effects of process variables, catalysts and mode of catalyst addition, solvent properties, and recycle of SRC on oil production and coal conversion were also studied. 9 refs., 12 figs., 72 tabs.

Book excerpt: The concentration of hydroaromatics in a coal liquefaction solvent is regarded as a significant factor in the determination of solvent quality. An analytical method is described based on catalytic solvent dehydrogenation (CSD) for the measurement of transferable hydrogen, including hydroaromatic sources, in a solvent. The dehydrogenation of several model compounds in the presence of Pd/CaCO3 was conducted under batch conditions. Hydroaromatics containing six-member rings were found to dehydrogenate effectively. Lesser degrees of dehydrogenation were found for alkyl-substituted aromatics and saturated compounds. CSD was applied to a series of hydrogenated creosote oils plus several light recycle oils. The normalized H2 volumes obtained by CSD could be correlated with the coal-dissolution ability of the creosote oils. It was not possible to include the light recycle oils in the same correlation. 13C-NMR was used to measure the transferable hydrogen of selected hydrogenated creosote oils and light recycle oils. Values of transferable hydrogen determined by 13C-NMR were generally larger than the corresponding values obtained by CSD. A smooth correlation was found between coal conversion and transferable hydrogen as measured by 13C-NMR. The light recycle oils could not be fitted to the curve defined by the creosote oils. Minerals indigenous to coal provide an internal but weak source of catalytic activity during liquefaction reactions. A sensitive probe reaction, cyclohexene hydrogenation/isomerization, was used to compare the catalytic activity of several clay minerals, oxides used as catalyst supports, pyrite and liquefaction residue ashes.
