The catalytic upgrading of Short Contact Time (SCT) coal extract in bench-scale stirred autoclave reactors has been shown to be an effective way of inexpensively simulating PDU LC-Finer units. Tests were carried out to determine the effect of temperature staging in single and series reactor configurations on product quality with respect to being a good hydrogen donor solvent. It was shown that two series reactors operating in the range of 740 to 770/sup 0/F produced the most effective solvent for coal conversion under SCT conditions. A correlation was developed which related coal conversion with the solvent quality parameters of the solvent. Four different catalysts were run in the stirred autoclaves including an aged Shell 324M NiMo, a fresh Shell 324S NiMo, a Shell 324 low density NiMo, and a fresh Shell 454 NiW species. Although differences in operating conditions precluded direct comparisons, the NiW extrudate catalyst produced a poorer quality solvent than the NiMo catalysts. Additionally, runs performed in single reactor LC-Finer PDU's have been used to provide simulated interstage reactor samples for the ITSL LC-Finer PDU. The conversion of 850/sup 0/F+ material and denitrification were found to require more than one reactor to achieve maximum levels. Hydrogenation, however, occurs largely in the first reactor, particularly with Illinois 6 coal extract when compared with Wyodak coal extract. A good quality recycle solvent for the SCT reaction is produced from the single reactor LC-Finer. 4 refs., 41 figs., 40 tabs.
