“…The aliphatic, aromatic and polar components of the maltenes ranged from 47 to 53%, 15 to 20% and 34 to 36%, respectively. There is fairly good agreements between these values and those previously reported for Nigeria tar sand maltenes (51, 15 and 34%) [3]. The polar fraction (nitrogen, sulphur and oxygen containing compounds) constitutes the major portion of the hydropyrolysis products of the asphaltene ($80%) with the aliphatic and aromatic fractions values ranging from 11.8 to 13.8% and 7.6 to 8.6%, respectively.…”

“…Also abundant within the asphaltene structures are the aliphatic hydrocarbons, which are covalently bound to the aromatic rings [10,11]. In highly biodegraded oils these aliphatic hydrocarbons are believed to represent a remnant of the 'original oil' [3,6], and have been found useful in oil/oil and oil/source rock correlations [3,4,6,10,12,13].…”

“…Meanwhile the occluded hydrocarbons inside the asphaltenes were released, which can be distinguished from the adsorbed hydrocarbons obtained from the initial asphaltenes by acetone extracting (Liao et al, 2006b;). The hydrocarbons occluded inside the asphaltenes were well protected from secondary alterations in the reservoir due to the macromolecular structures of asphaltenes, therefore they retain the early generation information of crude oils (Behar et al, 1984;Ekweozor, 1984Ekweozor, , 1986Peng et al, 1997Peng et al, , 1999. Thus, the geochemical features of the compounds adsorbed and occluded inside asphaltenes can provide useful information concerning the charging or mixing processes of oils.…”
