Solid-state 13C n.m.r. (CP/MAS-13C n.m.r.) spectroscopy provides a direct method for estimating potential oil yields of oil shale formations. Relative aliphatic resonance areas correlate linearly with oil yield and provide a method for oil yield estimation that obviates the need to determine weight

than the initial fraction, which contains more aliphatic and hydroaromatic material. Proton n.m.r. data are consistent with these aromaticity results. ## Conclusions The initial results reported here from tests in the FDU using both coal-derived distillate and residuum show that the unit is basic
