Coal preparation for two stage liquefaction. Quarterly report, January 1-March 31, 1984

Technical Report ·
OSTI ID:5069246
;
Quantities of Illinois No. 6 and Wyodak coals have been requested together with heavy liquid products obtained by liquefaction of these coals in the Wilsonville and Lummus Two Stage Pilot plants. These materials will be used in both pretreatment and liquefaction experiments. A literature survey has been conducted to provide information about the current state of knowledge concerning the separation of coal constituents and the influence of coal characteristics on liquefaction behavior. This survey is still in progress. Coal samples from an earlier and detailed controlled fractionation of Illinois No. 6 coal and prepared for examination by optical microscopy have been obtained. Originally these samples were examined to follow changes in mineral matter (pyrites) or fractionation. They will be reexamined in this project to follow changes in maceral composition through the various stages of fractionation and it is anticipated that the information will be a valuable asset to the proposed research. Currently, major items of equipment for an autoclave reactor system have been ordered and are awaiting delivery.
