Catalytic reaction pathways for fluoranthene hydrogenation and hydrocracking were determined at 310 to 380/sup 0/C and 153 atm of total pressure. Fluoranthene hydrogenation was catalyzed by a presulfided NiW/Al/sub 2/O/sub 3/ catalyst, whereas its hydrogenation and subsequent hydrocracking were catalyzed by a presulfided NiMo/zeolite-Y catalyst. The activities for conversion of fluoranthene were comparable, as the fluoranthene disappearance rate constant kappa (cm/sup 3/ of solution/(g of catalyst s)) = 0.28, 0.70, and 1.2 at 320, 350, and 380/sup 0/C, respectively, for the reaction catalyzed by NiW/Al/sub 2/O/sub 3/, suggesting Arrhenius parameters of (log A (cm/sup 3/ of solution/(g of catalyst s)), E/sub act/ (kcal/mol)) = (6.4, 18.7), whereas kappa = 0.27, 0.63, and 1.00 at 310, 350, and 380/sup 0/C, respectively, with (log A, E/sub act/) = (4.8, 14.2) for the reaction catalyzed by NiMo/zeolite.
