Abstract
In this study, waste chicken eggshell-derived CaO particles were synthesized as heterogeneous catalyst, and their structural and morphological properties were evaluated. CaO was used as a catalyst in ultrasonic-assisted biodiesel production from waste cooking oil (WCO). Response surface methodology (RSM) based on central composite design (CCD) was applied to investigate and optimize the influence of reaction parameters, such as catalyst loading (6–12 w/w%), methanol to oil ratio (6:1–12:1 m/m), ultrasonic power (150–300 W), and reaction time (20–40 min), on biodiesel yield and specific energy consumption (SEC). The results showed significant effects of the parameters on the biodiesel yield and SEC, except for the effects of molar ratio on SEC. Moreover, the optimal reaction conditions were a catalyst loading of 6.04 w/w%, methanol to oil molar ratio of 8.33 m/m, ultrasonic power of 299.66 W, and reaction time of 39.84 min, leading to a biodiesel yield of 98.62% and SEC of 5.01 kJ.g−1.
