| Popis: | The Colorado School of Mines is performing a research contract under the sponsorship of the Office of Coal Research, the State of Colorado, and the Office of Research Services of the Colorado School of Mines to determine the importance of operating variables and raw material properties on coal desulfurization via the solvent refining process. The solvent refining process is being studied in bench-scale, high-pressure, high-temperature, rocking-bomb autoclave batch reactors. The liquid product from the reactor is vacuum distilled to give a solvent refined coal, and the refined coal product is analyzed for sulfate, pyritic, and total sulfur content, with organic sulfur content being determined by difference. Initially five variables were studied: temperature, partial pressure of hydrogen, solvent-to-coal ratio, solvent type, and reaction time. The reaction time was determined to be statistically unimportant, and anthracene was shown to be the better solvent. Further experimental work has been compl... |
