A study was carried out on oils produced from co-processing of a coal and a petroleum catalytic cracking slurry (PCCS) in a 50-litre autoclave. Under the co-processing conditions used, the oil yield increases with an increase in co-processing temperature and time. It was also found that the co-processing under N₂ atmosphere yields significantly more oil than under H₂ atmosphere. The catalyst addition and catalyst type showed no significant effects on the oil yield. These results may be related to the properties of PCCS. The oil properties such as boiling point, sulfur distribution and chemical composition were investigated by FTIR and HPLC.
