N2 - The upgrading of heavy crude oils, which have a global volume of about 3-4 times that of conventional crudes, has become a economically viable option. However, the processing of these heavy crudes is complicated due to the increase of their inherent complexity. An understanding of the structures present in these types of samples is vital to improve the efficiency of their processing. In this regard, nuclear magnetic resonance (NMR) provides a quantitative technique for the type of hydrogen and carbon atoms present in their structure. Moreover, the combination of this technique with elemental analysis and an accurate number average molecular mass (Mn) allows the calculation of certain useful average structural parameters (ASP). Herein we report the average structural parameters (ASP) calculated for solubility fractions of an Athabasca bitumen (tar sands) by means of a combination of Mn estimates (from SEC and LD-MS), elemental analysis and NMR data.
