Kwon, K C

Effects of heating rates on liquefaction of both Wyodak coal and Kentucky No. 9 coal were investigated in the presence of various hydrogen donor solvents as part of Task I. A series of coal liquefaction runs were conducted for Wyodak coal, increasing coal liquefaction temperatures from 200 C or 300 C up to 380 C and holding liquefaction temperatures at 380 C for 15 min. The main objectives of this study are to identify roles of hydrogen donor solvents in the early stage of liquefying Wyodak coal and to compare these results with the previous results of Kentucky No. 9 coal runs, which were reported in the Quarterly Progress Report for the period of July-September 1985. Another series of coal liquefaction experiments were performed, using Kentucky No. 9 coal and hexadecane as a physical solvent, instead of 1-methylnaphthalene to investigate interactions between hydrogen donor solvents and physical solvents in the early stage of liquefying Kentucky No. 9 coal. 12 figs., 6 tabs.
