An Enhanced-Solvent Deasphalting Process: Effect of Inclusion of SiO2 Nanoparticles in the Quality of Deasphalted Oil

Table 5

Ostwald-de Waele estimated parameters from rheological experiments for the DAO after the SDA and -SDA processes with an SOR of 8 at 25°C using SiO2 nanoparticles at a dosage of 5 wt% and an SOR of 8 with -pentane as the solvent.
