摘要

Non-edible waste cooking oil (WCO) is an eco-friendly, renewable biomass that holds significant interest and commercial relevance in the lubricant and energy sectors. The present study demonstrates a novel approach for developing sustainable biolubricant formulations by incorporating garlic essential oil extract into WCO at three distinct concentrations (10%, 20%, and 30% v/v), combined with N-150 mineral base oil. These formulations are designated as GL-10, GL-20, and GL-30. Garlic essential oil inhibits the thermal oxidation of WCO due to its antioxidant properties. Tribological evaluations were conducted using the ASTM D4172 method, while thermophysical properties, such as viscosity index, pour point, and flash point, were assessed using ASTM D2270, ASTM D97, and ASTM D93 methods, respectively. Rheological studies were performed using an Anton Paar MCR-72 rheometer, and tribological analysis was carried out with a four-ball wear tester.

The thermophysical evaluation demonstrated excellent properties for the formulated biolubricants. The viscosity index increased with the rising concentration of WCO, while the pour point decreased, improving performance at extreme temperatures compared to the N-150 mineral base oil. Rheological studies revealed non-Newtonian behavior with increasing shear rate. Tribological tests showed a 5% reduction in wear scar diameter and a 13% reduction in the coefficient of friction compared to the mineral base oil. This research presents a straightforward and eco-friendly method for directly utilizing waste cooking oil in sustainable biolubricant formulations.
