For the past several years this laboratory has been studying water assisted coal liquefaction. Initial experiments were designed to determine whether water could replace all or part of the donor solvent in coal liquefaction. More recent work has focused upon the chemical reactions of coal models in supercritical water. For the past year efforts have centered upon the study of two distinct coal model compound systems (bibenzyls and benzyl phenyl ethers) with water under liquefaction conditions. This research is intended to further evaluate the chemical role of water above its critical temperature in the conversion of coal to a liquefaction product. Results are discussed.
