An extensive array of Short Contact Time (SCT) experimental matrices were investigated in support of Integrated Two-Stage Liquefaction Process Development Unit (ITSL PDU) operations. Various matrices explored the operating parameters and pasting solvents required to maximize coal dissolution and conversion to liquids. The effects of added pyrite were also investigated. Several blends of Anti-solvent Deashing (ASDA) underflow as well as LC-Fining (LCF) feed were used to correspond with different PDU process configurations. Solvents from both Wyodak subbituminous and Illinois 6 bituminous coals were run to measure solvent quality for coal dissolution. These solvents were prepared from various ITSL process configurations and process parameters. In support of the SCT microautoclave experiments, extensive analytical data was statistically analyzed. Correlations based on LCF solvent properties were developed and will be useful in predicting the degree of coal dissolution. Pressure versus residence time effects were also explored in the microautoclave reactor system. Previous data from the ITSL data base were analyzed for the effect of low hydrogen pressure on coal dissolution. The spent catalysts from the three LCF reactors of the second stage of the ITSL PDU process were tested for hydrogenation activity as measured by naphthalene hydrogenation. The effects of the regeneration of whole spent catalysts and ground spent catalyst were explored. Several catalysts were investigated in a mode of accelerated deactivation. The value of presulfiding hydrogenation catalysts for upgrading coal extracts was also investigated. Two matrices were conducted to determine the thermal effects on coal extracts without a catalyst charge to the microautoclave reactor system. 81 figs., 18 tabs.
