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

Table 6

Ostwald-de Waele estimated parameters for rheological experiments on DAO after -SDA with SiO₂ nanoparticles dosage of 2.5 and 10 wt% at SOR = 8 at 25°C and using -heptane as the solvent.

Nanoparticles dosage (wt%)	Parameter
	K (cP·s)	(dimensionless)	RSME%
2.5	15802	1.001	0.58	0.19
10	9982	0.996	0.69	0.27
