Abstract
The global energy crisis and the rise in carbon emissions have driven the development of environmentally friendly alternative energy sources. One potential energy source is biodiesel derived from used cooking oil, which can be utilized as a renewable fuel. This study aims to determine the effect of bentonite addition on the combustion characteristics of used cooking oil biodiesel droplets. The mixture variations used consist of B0 (0%), B10 (10%), B20 (20%), and B30 (30%) bentonite based on the total mass of biodiesel. The experiments were conducted experimentally by observing four main parameters: ignition delay time, temperature distribution, burning rate, and flame visualization. The results showed that the addition of bentonite affected the combustion characteristics of the droplets. The 10% (B10) mixture exhibited the best combustion performance with the fastest ignition delay time of 1.334 s, the highest maximum temperature of 448.736°C, a burning rate of 1.116 mm²/s, and the most stable and efficient flame. At higher concentrations (B20 and B30), combustion performance decreased due to increased viscosity and particle agglomeration, which hindered heat and oxygen diffusion. Therefore, the addition of bentonite at the optimum concentration can enhance the thermal efficiency and flame stability of used cooking oil biodiesel, making it a promising environmentally friendly alternative fuel.
