A detailed analysis was conducted on the pyrolysed samples after an exhaustive soxhlet extraction with benzene as solvent. The percentage of the oil obtained at different temperatures increases as the temperature increases. Column chromatographic method was used to elute five different fractions comprising: saturates, monoaromatics, diaromatics, polyaromatics and polars/resins. These results indicate that tar sands can be potential sources of feedstock for the petrochemical industry in the country. ER -
