Abstract

The authors carried out studies to obtain a more complete understanding of the mechanisms for the principal reactions which occur during the catalyzed 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. On the basis of these investigations, a mechanism is proposed for the hydroliquefaction process which emphasizes the role of catalysts inhibiting repolymerization reactions, the significance of interconvertibility of coal-derived products and the importance of hydrogen donation from molecular hydrogen and the vehicle tetralin.
