✦ Synopsis

Pale, medium-light and medium-dark lithotypes of Yallourn coal were hydrogenated with and without ZnCl,containing catalysts (400X, 9.8 MPa H2 and 3 h). The degree of hydroliquefaction wasexamined petrographically. Without catalyst, the amounts of water produced can be correlated with the amounts of humodetrinite; whereas with catalyst, either humotelinite or humocollinite may contribute to coal liquefaction in addition to humodetrinite; with pale lithotypes in the presence of catalyst, three submaceral groups may be converted.
