Abstract
Samples of Beypazarı, Elbistan and Kangal were hydrogenated in a bomb reactor, in the presence of tetralin and without catalyst, under 395°C temperature and 7MPa cold hydrogen pressure conditions for 17 minutes. Conversion, liquid yield and preasphaltenes-asphaltenes-oil distribution were determined by a standardized procedure. The Beypazarı sample gave higher conversion (91 %) and liquid yield (64 %) in comparison with the others, but the lightest liquid was derived from Elbistan sample. The consistency of the experiment was verified by total mass and sulphur balances, which gave closures around 100 %.
