The overall aim of our recent studies has been to obtain a more complete understanding of the mechanisms for the principal reactions which occur during the catalysed hydroliquefaction of low rank, high oxygen containing (ca. 25 wt% db) coals. The results of 70 ml batch autoclave studies with and without added catalysts on Victorian brown coal, on a number of different coal derived products and on related model ether compounds are discussed herein. More complete details of various aspects of this work may be found elsewhere. On the basis of these investigations a mechanism is proposed for the hydroliquefaction process which emphasises the role of catalysts in inhibiting repolymerisation reactions, the significance of interconvertibility of coal derived products and the importance of hydrogen donation from molecular hydrogen and the vehicle tetralin.
