Abstract: In the paper, group composition of the natural bitumen of the Beke oil sand were studied. During the experiment, the they separated by chromatographic method in a Soxhlet apparatus and determined the percentage of oil, resin and asphaltene fractions of natural bitumen. Natural bitumen was analyzed at a Fourier transform IR-spectroscopy Spectrum-65 with 450-4000 cm−1 range. Comparing the results of elemental analysis of resin and asphaltene, it was observed that asphaltene contains more elements except carbon and hydrogen than resin. Morphological structure of asphaltene samples were studied by the scanning electron microscope (SEM) at 20 KV voltage and 0.003 Pa pressure.
