Abstract
Upgrading of coal-derived liquids is an important aspect of direct coal liquefaction and may determine when such liquefaction will be economically feasible. Coal derived liquids (CDL) are largely unacceptable as refinery feedstocks because of their high heteroatom and metals content and their aromatic nature. Heteroatomic removal and metals reduction are part of some petroleum refinery processing, but the presence of condensed ring polyaromatics is unique to liquids from coal. Successful upgrading processes will have to achieve significant reductions in the content of these aromatic components. Methods will also have to be found to reduce the buildup of coke on the catalyst surface, which has been the main reason for decreasing catalyst-bed activity during upgrading processing.
