“…They introduced the concept of structure-oriented lumping to deal with the sample complexity within the limitations of the then-available analytical techniques (7 ). Another seminal series of reports, by Boduszynski and others, on the composition of heavy petroleum drew on a variety of analytical techniques to derive a surprisingly inclusive description of complex petrochemicals (8)(9)(10)(11). The high mass resolution and high mass accuracy of FT ion cyclotron resonance (FTICR) MS made it an attractive candidate for complex mixture analysis when it made its debut in the mid-1970s, although those capabilities were fully realized only in the last decade or so (12)(13)(14).…”

“…Figure 8 presents the viscosity measurements at 37 • C of the product oil, maltene-asphaltene and maltene fractions, while • API gravity measurements at 24 • C of the product oil as well as maltene fraction, are shown in Figure 9. High temperature simulated distillation curves for the product oil, from select runs, with distillation cut points shown as volatiles (<n-C 10 , T < 175 • C), medium range distillates (n-C 10 -n-C 20 , 175 [58,59] are presented in Figure 10. In order to exclude the effect of sample ageing, the volatile yield between Figure 7 and 10 was synced by shifting the simulated distillation curves accordingly.…”

“…The extent of increase is likely linked to the asphaltene yield of the sample, as well as losses of volatiles experienced during solvent evaporation. Asphaltenes have a very strong effect on heavy oil viscosity, and the concentration of asphaltenes increase upon loss of the volatile components [58][59][60][61][62]. For example, the TC raw drill cuttings and supported drill cuttings runs had a higher maltene-asphaltene viscosity than the TC control run, as the asphaltene yield was higher for those runs coupled with higher total losses.…”

Hydrocracking of Athabasca Vacuum Residue Using Ni-Mo-Supported Drill Cuttings

Ni-Mo supported drill cuttings were used to catalyze the hydrocracking (HDC) of Athabasca vacuum residue (AVR) in an autoclave. Drill cuttings are a common waste product that are, depending on their origin, plentiful in acidic sites. The catalyst was prepared using the wet impregnation method. HDC was carried out at both low and high H2 pressure at 400 °C. Control thermal cracking (TC) and HDC runs with and without raw drill cuttings were performed to better examine the role of the supported drill cuttings catalyst. The quality in terms of viscosity and °API gravity, and the yield of various fractions making up the product oil were used to gauge the performance of the catalyst. Similar temperature and energy profiles between TC and HDC suggested strong overlap between the two different reactions, despite H2 presence. Nevertheless, supported drill cuttings runs at high H2 pressures promoted H2 consumption to a strong extent. Consequently, the liquid yield was the highest (~75 wt.%) and the coke yield was negligible. High temperature simulated distillation results revealed a residue conversion of ~55% for both low and high pressure HDC catalytic runs. The product oil quality with respect to viscosity and °API gravity was also found to be comparable between the low and high pressure HDC catalytic runs. Accordingly, no trade-off between liquid yield and quality was incurred at high H2 pressure. Effectively the supported drill cuttings drastically reduced coke formation, while maximizing the yield of the desired liquid product.
