Abstract

Abstract Catalytic upgrading of SRC (solvent refined coal) derived from short contact time pyrolytic liquefaction of Wandoan subbituminous coal was carried out. The upgrading with unsulfided and sulfided nickel–molybdenum catalysts produced about 77 wt% and 85 wt% of oil plus light distillates from the SRC, respectively. The reactions occurring during the upgrading process were assessed by referring to the hydrocraking of related polycyclic aromatic hydrocarbons.
