Abstract A Saskatchewan heavy oil was processed with coal additives in a tubular reactor packed with procelain berl saddles at 400–480°C and atmospheric pressure. For comparison purposes, blank experiments in the absence of coal additive were also carried out. The results indicate that considerable reduction in viscosity and increased distillate yields can be achieved by processing heavy oil with coal additive. The API gravity of the liquid product is also improved. Increased amounts of gaseous products with changed composition are obtained in the presence of coal. Under certain conditions, significant dissolution of coal occurs even at the relatively mild conditions used.
