This report presents the operating results for Run 247 at the Advanced Coal Liquefaction R and D Facility in Wilsonville, Alabama. This run operated in a Two-Stage Liquefaction (TSL) mode using Illinois No. 6 bituminous coal from the Burning Star mine. The primary run objective was to obtain performance data for the TSL system and the individual process units with particular emphasis on hydrotreating catalyst performance. 266 tons of coal were fed in 2845 hours of operation. The run configuration was a Reconfigured Integrated Two-Stage Liquefaction (RITSL) mode. In RITSL, the products from the thermal (first stage) unit are sent to the hydrotreater (second stage) unit without prior deashing. The hydrotreated resid and ash are sent to the Critical Solvent Deashing Unit, and the deashed resid is then recycled to the thermal unit. Operating conditions were adjusted to obtain high coal conversions, acceptable deashing performance, and an ''all-distillate'' product slate. Nine operating periods were defined based on testing at different sets of operating conditions. Elementally-balanced yields were calculated for several days during each operating period. Averaged yields and operating conditions for these periods are presented throughout this report. For five of the operating periods, blends of the distillate products were prepared, and detailed product quality analyses were done for each boiling point cut. A special radioactive tracer study was also conducted to assess the level of mixing in the TLU dissolver. 16 refs., 38 figs., 37 tabs.
