;
Middle distillate fractions of syncrudes from Athabasca Oil Sands were evaluated for suitability as feedstocks in the catalytic conversion to diesel fuel meeting cetane number specifications. Hydrogenation of aromatic components to napthenes under severe conditions (380 to 400/sup 0/C, 2500 psig) using sulfided CoO/MoO/sub 3/ and NiO/WO/sub 3/ over ..cap alpha.. . Al/sub 2/O/sub 3/ in a previously described catalyst testing system. Reaction products were analyzed for aromatic carbon content using C/sup 13/ NMR spectroscopy and pseudo first order rate constants and activation energies (15.0 and 14.2 kcal 1 g-mole, respectively) were determined by regression analysis. At optimum conditions 97% aromatic conversion was obtained with the Ni-W catalyst. Product diesel fuel cetane number (42) was within specifications. Co-Mo catalyst was significantly less active.
