Özet
Beypazari oil shale was subjected to supercritical fluid extraction with water and toluene separately. Considerable differences were observed in the yields (wt %) and compositions of the oils obtained from oil shale SCW (supercritical water) gave a higher conversion degree of kerogen in oil shale than SCT (supercritical toluene), whereas oil yield in SCT was 41% more than that in SCW. Oils having more asphaltenic and polar compounds were obtained from SCW. Although the polar contents decreased in SCT oils with increasing temperature, they increased in SCW oils. No n-alkenes-1 were observed in the aliphatic fraction of SCW extraction oil. The temperature affected the isomerization of aliphatics in SCT oils. The molecular weight of oils was affected basically by the temperature at both supercritical fluids.
