Separation, characterization and instrumental analysis of polynuclear aromatic hydrocarbon ring classes in petroleum
To develop effective utilization technology for heavy streams from conventional fuels and unconventional resources such as heavy oils and oilsand bitumens, detailed information on the chemical composition of the feedstocks is needed. Attempts were made during the seventies to modify the API Project 60 scheme of analysis or to develop chemically more efficient, and less time-consuming, separation and characterization methods. These attempts aimed to improve characterization by separating the samples into concentrates of different structural types. Samples throughput was increased by using pressure and higher performance chromatographic systems. Other valuable contributions, such as coal-liquid characterization in terms of different chemical functionalities have also been made. The separation of aromatic ring classes and characterization or identification of their major components was our primary objective in this study. A silica-R(NH/sub 2/)/sub 2/-based HPLC system was used in our laboratory to study the analytical potential of this approach; the work was described in a previous publication. In the present study, the applicability of HPLC separation by this system and instrumental spectrometric characterization of 3- and 4-ring PAHs isolated from two Canadian oils were investigated. The oils used, Medicine River and Lloydminster, are examples of hydrocarbon-dominated materials representing light and heavy processing feedstocks, respectively.
