The investigation of various Two-Stage Liquefaction (TSL) process configurations was conducted at the Wilsonville Advanced Coal Liquefaction R D Facility between July 1982 and September 1986. The primary objective of the TSL program has been to develop a commercially feasible method for conversion of coal to residual oils or distillate fuels. The facility combines three process units. There are the liquefaction unit, either thermal (TLU) or catalytic, for the dissolution of coal, the Critical Solvent Deashing unit (CSD) for the separation of ash and undissolved coal, and a catalytic hydrogenation unit (HTR) for product upgrading and recycle process solvent - replenishment. The various TSL process configurations were created by changing the process sequence of these three units and by recycling hydrotreated solvents between the units. This topical report presents a description of the TSL configurations investigated and an analysis of the operating and performance data from the period of study. During this period, Illinois No. 6 Burning Star Mine coal and Wyodak Clovis Point Mine coal were processed. Cobalt-molybdenum and disposable iron-oxide catalysts were used to improve coal liquefaction reactions and nickel-molybdenum catalysts were used in the hydrotreater. 28 refs., 31 figs., 13 tabs.
