Production and Screening of Carbon Products Precursors from Coal

Michael A. Nowak of DOE/FETC contacted Richard A. Winschel of CONSOL, Inc., for samples of coal-derived liquids for evaluation as feedstock materials for anode coke and binder pitch. Two samples have undergone preliminary evaluation by the Chemical Engineering Department at West Virginia University. The results of the tests are presented herein. The first sample is identified as Kerr-McGee Light Phase. The material was produced using the Kerr-McGee critical solvent deasher (CSD, also known as the ROSE process). The CSD unit produced three streams; an ash concentrate, heavy solvent refined coal (SRC), and light SRC products. The sample examined by WVU is claimed to be the light-stream SRC
