During the third quarter of the program, experimental work had commenced on microautoclave evaluation of partially converted coal slurry obtained from PDU Run 260-03. Additional conversion of coal in the noncatalytic and catalytic tests was observed. However, the increase in coal conversion was lower than previous tests on the HRI-5887 shipment of Black Thunder Mine coal prepared by Empire Coke Company. Microautoclave tests on coal used as feed in the PDU Run 260-03 are being evaluated under the CTSL program. Retrofitting of a small continuous flow unit for fixed bed processing of partially converted coal slurry had commenced in June and is expected to completed by the end of July. The fixed bed test program is scheduled to start in mid-August. A batch of presulfided Shell S-317 1/20 in. trilobe catalyst had been obtained from Wilsonville and was characterized during this period. The Mo/Ni ratio of the presulfided trilobe catalyst was very similar to that of the fresh Shell S-317 1/32 in. extrudates. As a result of the presulfiding procedure, part of the pore structure (24%) was blocked by carbonaceous deposits. However, the pore size distribution of the trilobe catalyst remained about the same as the fresh 1/32 in. extrudate.
