Studies were carried out using subbituminous Wyodak and bituminous Kentucky coal to determine the effect of upgrading coal liquefaction recycle bottoms. In the liquefaction experiments, the reactor was charged with recycle solvent, solvent-refined coal (SRC) or SRC fraction and coal in a 1:1:1 weight ratio, and the reaction was carried out at 714/sup 0/K under hydrogen pressure. The results obtained indicated the importance of solvent composition on the coal liquefaction reaction. Maximum conversion seemed to be achieved with some degree of hydrogenation of the SRC, but the severity of the hydrogenation process was not clearly defined. Solvent fractionation may also result in increased distillate yields. (BLM)
