Techno-economic assessment of recent advances in direct coal liquefaction. [Lummus, Wilsonville, Hydrocarbon Research Inc. , Kerr-McGee, and Amoco]

Technical process performances and economics of DOE-supported two-stage coal liquefaction processes are compared in this report. In addition, selected single-stage coal liquefaction processes are analyzed using the same methodology to act as reference performance indicators. Two coal feedstocks are assessed - Illinois No.6 bituminous and Wyoming subbituminous. 31 refs.
