The experimental work was undertaken in a bench-scale flow system at 2000 psi with the oil and hydrogen percolating up through a fixed-bed of cobalt molybdate catalyst, i.e., the system was operated in a bottom-feed, mixed-phase mode. The range of temperatures investigated was from 320 to 420°C at liquid hourly space velocities of 1, 2, and 3 with a hydrogen flow rate of 5000 scf/bbl. The reference feed stock was a gas-oil prepared commercially (500-850°F) from Athabasca bitumen by delayed coking. This was compared to two experimentally produced gas-oils (650-975°F) generated by the thermal and catalytic hydrocracking of Athabasca bitumen in a Mines Branch pilot plant. The reaction characteristics of the three gas-oils were found to be very similar. Products comparable to ASTM Grades 4 and 5 fuel oils containing 0.3 to 1% sulphur could be produced at all the space velocities investigated at low reaction temperatures 340 to 400°C. Slightly more light-ends were produced with the lower-boiling coker gas-oil than with the higher-boiling hydrocracked gas-oils but the amounts involved were not large. No significant catalyst deactivation was observed with any of the feed stocks over the 45-50 operating hours involved in any of the series of experiments"--Abstract, p. i. |
