| Abstract | Characterization of bitumen, heavy oils, crude oil distillation residues and their processed products involves separation of the mixtures into several compound classes according to their molecular
structure. However, these fractions are still very complex and often need further separation in order to get a better insight into their composition as well as the processing reactions involved in their upgrading. In this paper, the polynuclear
aromatic fraction is divided into three subfractions by high performance liquid chromatography. Gas chromatography is then used to quantify these fractions and to determine their average molecular weight by a new method derived from simulated
distillation. Crude oil distillation residues and their hydrocracked products are used to demonstrate this method. |
