An LC-Fining PDU run indicated that 1/16-inch extruded catalyst has higher activity for 850/sup 0/F+ conversion and denitrogenation than the 1/32-inch extruded catalyst that has been the standard for all LC-Fining work on ITSL. A run with 1/64-inch catalyst was unsuccessful because of high pressure drop through the reactors. The integrated PDU operating with Illinois No. 6 coal and equilibrated solvent was started. LC-Fining activities followed the same trend as reported in the previous Topical Report for Run 3LCF8. The high initial activity for conversion declined and then levelled off at a catalyst age of 300 to 400 pounds of 850/sup 0/F+ feed per pound of catalyst. Conversion activity of the 650/sup 0/F+ feed, however, remained essentially constant, so that the product lightened with catalyst age. It is therefore possible to attain a -650/sup 0/F product with Illinois No. 6 coal, with little additional hydrogen consumption. The SCT product made at 840/sup 0/F is heavier and requires less hydrogen transfer to coal than the 865/sup 0/F product. Interstage samples taken from the LC-Fining unit showed that extract conversion is first order with respect to extract concentration. Catalyst analyses show a rapid initial laydown of metals, followed by slower additional accumulation. The metal laydown rate approximately parallels LC-Fining catalyst activity. An overall material balance early in LC-Fining Run 3LCF9 resulted in a yield of 3.07 barrels per ton of MF coal with a hydrogen efficiency of 11.96 pounds of C/sub 5/-850/sup 0/F distillate per pound of hydrogen consumed. The Integrated PDU operation and the Exploratory Expanded Bed Hydroprocessing Research program of this contract were concluded with this report.
