J. Yanik et al., CHARACTERIZATION OF THE OIL FRACTIONS OF SHALE OIL OBTAINED BY PYROLYSIS AND SUPERCRITICAL WATER EXTRACTION, Fuel, 74(1), 1995, pp. 46-50
Goynuk oil shale was subjected to slow pyrolysis and flash pyrolysis.
It was also subjected to super and subcritical fluid extraction with w
ater. Considerable differences were observed in the yields and composi
tions of the oils obtained under the four different conditions.
