| Popis: | Fourier transform infrared spectrometry (FTIR) spectra were measured for 16 distillation cuts obtained from two bitumens using a deep vacuum fractionation apparatus. Three regions of the spectra were deconvoluted into peaks each associated with a known type of vibration: (1) aliphatic C–H stretching in the 2800–3000 cm–1 region, (2) aliphatic C–H scissoring/symmetric deformation in the 1350–1400 cm–1 region, and (3) aromatic C–H out-of-plane bending in the 680–900 cm–1 region. The distribution of chemical structures in the oils were assessed, and preliminary correlations were identified between measured physical properties (density, atomic H/C ratio, and molecular weight) and the quantified peak areas obtained from the FTIR spectra. A preliminary method was proposed to generate physical property distribution data for crude oils based on distillation and FTIR data. The method predicted the density, atomic H/C ratio, and molecular weight of the distillation cuts, with average deviations less than 0.8, 1.4, ... |
