| Abstract: | Long residues (424°C +) from Athabasca, Cold Lake, Lloydminster, and Peace River were hydrocracked over a commercial NilMo on y-alumina catalyst at 430°C, 13.9 MPa (2000 psia). The conversion of residue fraction ranged from 55 to 68%, and was correlated with the concentration of carbon bound to aromatic rings in the feeds. Conversions of sulfur, Micro-Carbon Residue, and metals were all highest for Peace River feed, following the same ranking as residue conversion. Estimates for the breakage of carbon-carbon bonds and the uptake of hydrogen were diagnostic in interpreting the reactor performance. |
