Abstract: Solvent extraction method was used to separate the bitumen from oil sands. Ebullated bed
hydrogenation experiment, coking test of the bitumen oil and the dry distillation test were
compared. The results showed that with toluene as solvent bitumen oil recovery could be more than
90% in solvent extraction. The bitumen oil obtained from oil sands had the characteristics of high
density, high ash, high salt content, and the content of resin and asphaltene component of more
than 90 %. The removal of sulfur, carbon residue, nickel, vanadium rate reached 72.83%
66.85%, 96.16%, 98.24%, respectively, by ebullated bed hydrogenation with desalting bitumen
oil as raw materials, in which the conversion rates of resin and asphaltene were 73.53% and
98.63%, and hydrogenation product was the high quality of raw materials of deep processing. Tota
liquid yield was.64% and the yield o
coke was
28.95% by coking process with non-desalting
bitumen oil as the feed and the relatively effective utilization rate of resource was low. If the oil
sands were processed directly by dry distillation, the total recovery rate of bitumen oil was only
about 78.56%. Ebullated bed hydrogenation was the most effective method for bitumen oil
conversion with the effective recovery and utilization of oil sand bitumen
