Analytical results from two previously completed subtasks were received, which allowed for a more complete review of the results. In Subtask 2.3 (Solvent Hydrocracking with Catalysts), the product analyses from the microautoclave runs with the last three of the fourteen catalysts showed no advantage in the hydrogen to carbon ratio boost factor over the catalysts previously reported in the Oct-Dec 1984 Quarterly Report. However, for preasphaltene and asphaltene conversion, two of these last three catalysts, Shell 424 and Shell Amorphous HC, were among the top five or six performers. The effects on product solvent quality of pressure, temperature, and reaction time were determined for the Subtask 3.2 products (Catalytic Hydrogenation of Coal Extracts). The product hydrogen content showed an increase when doubling the microautoclave reaction time from one hour to two hours at 650F. But at 750F, the change in reaction time gave no significant hydrogen increase. The conversion of preasphaltenes and asphaltenes to oils showed a larger increase at 750F than at 700F when pressure was raised from 1500 psig to 2500 psig. Subtask 3.3 (Hydrocracking of Hydrotreated Extract and Solvents) was completed with 42 microautoclave catalytic hydrocracking runs. Five catalysts chosen from the Subtask 2.3 work were tested: Shell 324 Modified Ni/Mo; Shell 317 Ni/Mo; Procatalyse HR-941 Ni/Mo; Katalco NM-506 Ni/Mo; American Cyanamid 1442B Co/Mo. For maximum 650F/sup +/ conversion, the American Cyanamid catalyst and the two Shell catalysts are the best candidates for future work. The first two of three scheduled 15-day continuous catalyst aging (CCA) hydrogenation runs were made in Subtask 4.1 (Continuous SCT Extract Hydrogenation). Shell 324M and Shell 317 nickel-molybdenum catalysts were used to hydrogenate a deashed SCT feedstock to the optimum 7.5 to 7.9 wt. % hydrogen level. Both runs achieved this goal. 8 figs., 10 tabs.
