In a batch reactor screening of silica-supported molybdenum catalysts, it was determined that cobalt and nickel promotion was ineffective and that the silica based catalysts were generally much less active than catalysts prepared on other supports and tested previously. Batch reactor tests were also conducted on a series of nickel molybdate catalysts prepared from titania-alumina composites. The titania-alumina ratio was varied from pure alumina to pure titania. An optimum in activity for specific gravity reduction was observed between the 10 and 55 mole percent titania composition, and this roughly corresponded to a maximum in pore volume in the 60 to 200 A diameter range. A new feedstock was prepared by spiking a mildly hydrogenated creosote oil (HCO-1) with 20% residuum material from Wilsonville Run 247. A 450 hour deactivation run with the new feedstock and Amocat 1A indicated that the addition of residuum to the distillate feedstock did not result in a more rapid deactivation. A process variable study was conducted at the end of the deactivation run and kinetics models were developed for specific gravity reduction, hydrogen uptake and hydrodenitrogenation. 9 refs., 11 figs., 9 tabs.
