This program combines a research study on Catalytic Expanded Bed Hydroprocessing of Coal Extracts and the operation of an Integrated Two-Stage Liquefaction Process Development Unit. The integrated operation with Indiana V coal was completed with the conclusion of LC-Fining Run 3LCF7. The first of three 29-day diffusional study runs, PDU Run 4LCF-2, was completed on Shell 324 NiMo 1/32-inch extruded catalyst. The run was made in a new LC-Fining PDU that has three reactors in series and is capable of providing interstage samples between the reactors. Some catalyst deactivation for conversion was detected, but no decline was observed for denitrogenation. Both percent conversion and percent denitrogenation increased with decreasing 850/sup 0/F+ concentration in the feed. LC-Fining Run 3LCF-7 was completed with a final catalyst life of 1070 pounds of 850/sup 0/F+ feed per pound of catalyst. Conversion activity held constant for the entire run while denitrogenation activity declined. The increase of nitrogen in the product was found to be principally in the unconverted 850/sup 0/F+. Approximately 70% of the SCT paste solvent consisted of LC-Fining heavy oil product, including unconverted 850/sup 0/F+. This solvent continued to provide almost all the hydrogen for liquefaction of the Indiana V coal. The hydrogen-transfer capacity of the solvent was unaffected by LC-Fining catalyst age. Hydrogen consumption and C/sub 1/-C/sub 4/ yields increased with SCT residence time, while 850/sup 0/F+ yields decreased with 850/sup 0/F+ concentration in the recycle solvent. The integrated PDU is being prepared for a program on Illinois No. 6 coal.
