Hydrogenation of aromatic compounds catalyzed by sulfided CoO-MoO/sub 3//. gamma. -Al/sub 2/O/sub 3/
Hydrogenation of aromatic compounds catalyzed by sulfided CoO-MoO/sub 3//..gamma..-Al/sub 2/O/sub 3/ was investigated with batch and flow reactors at 275 to 350/sup 0/C and pressures near 100 atm. The reactants included benzene, biphenyl, dibenzothiophene, naphthalene, 2-phenylnaphthalene, and benzo(b)naphtho(2,3-d)thiophene. The reactivity for ring saturation was about an order of magnitude greater for the latter three ((substituted) naphthalenes) than for the others ((substituted) benzenes). Sulfur in a reactant molecule slightly increased the reactivity of a neighboring ring for hydrogenation. Dibenzothiophene hydrogenation was not inhibited by H/sub 2/S, but biphenyl hydrogenation was moderately inhibited by H/sub 2/S, and dibenzothiophene hydrogenolysis was strongly inhibited by H/sub 2/S. These and other results suggest that the reactant to be hydrogenated is ..pi..-bonded at exposed Mo cations, where H/sub 2/S undergoes weak competitive adsorption and bases like acridine undergo strong competitive adsorption. 22 references, 2 figures, 1 table.
