Advanced Coal Liquefaction Research and Development Facility, Wilsonville, Alabama
This report presents the results from Run 258 at the Advanced Coal Liquefaction Pilot Plant at the Clean Coal Research Center, Wilsonville, Alabama. The run began on May 19, 1989 and continued through November 8, 1989, operating in the Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) thermal/catalytic mode processing subbituminous coal. Both reactors were operated at half-volume. Coals from two different mines were processed in this run -- a Spring Creek mine (Anderson-Dietz seam in Montana) and a Black Thunder mine (Wyodak Anderson seam in Wyoming) -- to determine the preferable coal for future subbituminous coal liquefaction processing. (Tests were conducted to investigate the effects on coal conversion of increasing the iron oxide concentration in the coal feed slurry and to study the effects of increasing the coal feed rate and the first stage thermal temperature while maintaining equivalent thermal reaction severities). The effects of space velocity, recycle process solvent composition, first and second stage reactor temperatures, and coal feed rate were also investigated. An aged catalyst from a previous Wilsonville run was charged to the second stage reactor to eliminate run time used to age catalyst to equilibrium age. Catalyst replacement started at the beginning of the run and continued until October 11, 1989. At that time, the aged catalyst was removed from the reactor and was replaced with fresh presulfided catalyst to determine a deactivation rate with Black Thunder coal. Batch deactivation continued until the catalyst reached an age equivalent to the desired replacement rate, after which replacement resumed. 96 figs., 27 tabs.
