A coker distillate of Athabasca bitumen was hydrogenated over a fixed bed of cobalt molybdate on alumina catalyst. The effect of reaction pressure on the rate of catalyst deactivation was investigated at 896°F., an hourly space velocity of 2.0 and pressures from 1,000 to 3,000 p.s.i. The following expression was derived from the results of these experiments which relates reaction pressures and the hourly increase of the oil product specific gravity at these conditions.\documentclass{article}\pagestyle{empty}\begin{document}$$ \frac{{\Delta S.G.}}{{\Delta \theta }} = \frac{{1.24 \times 10^6 }}{{P^{3.1} }} $$\end{document}The yield and quality of the hydrogenated oil products and the relative hydrogen consumptions were determined at the following operating conditions:1. Pressure—1,000–10,000 p.s.i.; Temperature—797–896°F. Space velocity—2.0 hr. −1 . 2. Pressure—3,000 p.s.i.; Temperature—797–896°F. Space velocity—1.0–4.0 hr. −1 .
