摘要：

Timahdit oil shale was subjected to supercritical water extraction. The results reveal significant difference in oil yields and composition when compared with those obtained from conventional pyrolysis. In addition, the effect of temperature and residence time on the supercritical water extraction of oil was investigated in a set of three experiments. The results revealed that the yield and the fraction of paraffins and aromatics increase while the percentage of asphaltenes decreases as the temperature is increased from 380 to 400 degrees C. The residence time was found to affect the yield and the fraction of asphaltenes and polar compounds. (C) 1999 Elsevier Science B.V. All rights reserved.
