Description: Nano-adsorbents are widely used in the purification of contaminated industrial solutions. However, research into vegetable oil refining using nano-adsorbents has not been sufficiently investigated. Separation of nano-adsorbents from liquids can be challenging, primarily due to their size. Electrostatic field (E-field) treatments can remove minuscule particles from non-polar oils. In this study, nano-adsorbents were used to refine crude canola oil prior to the removal of the spent absorbent E-field treatment. Aluminum oxide effectively removed free fatty acids (FFA) from crude canola oil under moderate operating conditions (e.g., low dosage, short adsorption time, low agitation speeds, at room temperature), while also contributing to moderate neutral oil loss (4.38%). The ratio of Al2O3 nano-adsorbents to oil played a critical role in the efficiency of the neutralization. The Al2O3 nano-adsorbent treatment did not hydrolyze triglycerides in the canola oil. Treatment of crude oil with Al2O3 nano-adsorbents followed by E-field treatment removed 75.3 wt. % of absorbent from canola oil. Altogether, this study demonstrates the novelty in utilizing nano-adsorbent and E-field treatment for crude canola oil neutralization, which can benefit the economics of oil refining as well as the environmental impact (e.g., no chemical and water consumption, no sewage production) when compared with conventional methods.
