In this study, the synergistic effect of nanoparticles with vegetable oil has been investigated for the first time to prevent asphaltene precipitation. For this purpose, three types of nanoparticles (Al2O3, Fe3O4, and NiO) and three types of vegetable oil have been used to change the onset of asphaltene precipitation. Among the nanoparticles, the Al2O3 nanoparticle showed the best performance on the sorption of asphaltene particles and could increase the onset of asphaltene precipitation by 50%. Coconut oil, hazelnut oil, and wheat germ oil were also able to increase the onset of asphaltene precipitation up to 48%, 48%, and 50%, respectively. The synergistic effect of Al2O3 and wheat germ oil succeeded in increasing the onset of asphaltene precipitation and was able to increase the onset of asphaltene precipitation and it performed better than other nanofluids.
