The Integrated Two-Stage Liquefaction (ITSL) process consists of Short Contact Time (SCT) liquefaction, followed by Lummus proprietary Antisolvent Deashing (ASDA) and catalytic hydrogenation/hydrocracking by LC-Fining. The deasher underflow is the purge to rid the process of refractory material. Unconverted extract, heavy LC-Fining distillate products, and distillate from deashing constitute the recycle solvent used to slurry coal feed to the SCT reactor. The Final Report is composed of three volumes: the first volume includes a Technical Summary section and the main report on Task 2, Process Development Unit Integrated Operations. Task 1, Expanded Bed Hydroprocessing research on the catalytic second stage in prototype continyous units is described in Volume 2. Tables of operating conditions, results and product properties for Task 2 are reported in Appendix E. A microautoclave reactor system study of SCT coal dissolution parametes is presented in Volume 3. 89 figs., 19 tabs.
