Title
Activated red mud as a catalyst for the hydrogenation of coals and of aromatic compounds
Abstract
Red mud has been activated by dissolution in hydrochloric acid and reprecipitation with ammonia. The activated material has been evaluated as a catalyst for the hydrogenation of naphthalene, phenanthrene and pyrene and in the hydroliquefaction of both a high and low rank coal utilizing solvents of high and low hydrogen donating ability. Activation led to a substantial increase in the ability to hydrogenate the model compounds and a significant increase in oil yield was obtained in the hydroliquefaction of a low rank coal in the presence of a poor donor solvent. However, activation did not lead to significant increases in overall yields of liquids in other cases and the activated red mud was significantly less active than a commercial nickel-molybdenum-sulphur catalyst. © 1992.
