In the development of the Exxon Donor Solvent (EDS) process, bituminous and subbituminous coals have been processed in a one ton-per-day coal liquefaction pilot plant using the feed coal slurried with solvent and with or without bottoms recycle.

## Hydroprocessing of de-ashed coal liquid bottoms (DAO) derived from Victorian brown coal liquefaction was carried out in a fixed-bed reactor loaded with molybdenum catalyst. The conventional hydroprocessing catalyst is deactivated by the preasphaltene contained in the coal liquid bottoms. This d
