RAMOS, Daniel A. et al. DIRECT CATALYTIC LIQUEFACTION OF COALS. EFFECT OF THE TEMPERATURE. Rev.Colomb.Quim. [online]. 2010, vol.39, n.1, pp.131-139. ISSN 0120-2804.

A high volatile bituminous coal from the Department of Cundinamarca (Colombia), was liquefied in the presence of a polymetallic catalyst in a 500 mL batch reactor at 370, 410 and 450 °C under hydrogen atmosphere, using tetralin as hydrogen donor solvent and residence time of 1 h. When the catalyst was used and the temperature increased, the coal conversion and the oil yield increased too. The maximum oil yield obtained was 67% at 450 °C.
