Abstract
This report describes work done in a program designed to better understand and improve the Solvent Refined Coal and related liquefaction processes. It was determined that DMF/NH/sub 4/SCN was the best solvent system to use when analyzing SRC coal slurries by coulter counter. The agitation rate in SRC type processes was found to have little effect on the rate of particle dissolution, indicating little importance of liquid-solid mass transfer resistance. The variation in coal dissolution rate with solvent/coal ratio was also studied. In pretreatment study, NaOH was found to be effective in removing about 50 percent of the sulfur present in the feed coal. Iron containing compounds still represent the most active mineral catalysts tested to date. Preliminary separation of SRC fractions was made by GPC and the GC-FTIR system was partially completed. A separate abstract was prepared for the appendix.Keywords
