Feedstock for Demex deashing of coal liquids was prepared by liquefying a slurry of Illinois No. 6 coal in a coal-derived solvent. Of the moisture free slurry fed, 95% was obtained as feed to the Demex unit. The remainder was C/sub 6/- light ends. Coal conversion on a MAF basis was 92.5%. The Demex operation has been completed after overcoming problems with the bottoms product transfer system. The results are currently being evaluated and product analyses are in progress. The hydrotreating of the Demex product is to be started in early May.
