摘要

The integrated two-stage liquefaction (ITSL) process was a major step in the coal liquefaction technology development. This process consists of a thermal liquefaction unit, a critical solvent deashing unit, and a catalytic hydrotreater in series. The system is integrated by the recycle of hydrotreated resid and solvent to the thermal liquefaction stage. Five ITSL runs were completed at the Advanced Coal Liquefaction R and D facility using Illinois No. 6 bituminous coal and Shell 324 nickel-molybdenum catalyst. This report presents a systematic development of a simulation model to predict the yield structure, stream flow rates, and stream compositions for Illinois No. 6 coal liquefaction in the ITSL configuration. Kinetic models will be presented for first-stage thermal reactions and second-stage hydrotreating reactions using data from a batch autoclave and the pilot plant runs. The applicability of ASPEN (Public) to predict high pressure and high temperature vapor-liquid equilibrium separations in the ITSL process will be shown by comparing the predicted data with the actual plant data. Unit models will be presented for the three units. Finally, these unit models will be integrated into an overall simulation model using ASPEN. 150 refs., 58 figs., 45 tabs. (ERA citation 13:000033)
