چکیده
Biodiesel is a major renewable energy source derived from vegetable oils. Modern techniques are now required to produce biofuels, particularly biodiesel, to improve the efficiency and sustainability of the process. This study focuses on continuous biodiesel production from waste cooking oil via microwave-assisted transesterification in a flow process. Calcium oxide prepared from willow leaf extract was used as a catalyst at concentrations ranging from 1% to 4%, with a microwave power of 20% of the total 800W and an irradiation time of 0.5-7 min. The oil-to-methanol ratio was 50wt.%- 80wt.%, and the reaction temperature was 45-75 ℃. The results revealed that the waste cooking oil can be converted to biodiesel with a yield of (93.43%) in 5 min. with a 70wt.% oil/methanol molar ratio and 3wt.% catalyst. Also, the results indicated that the production of high-quality biodiesel, in accordance with ASTM standards, was facilitated under all operational conditions. The results suggest that microwave heating is a viable approach for achieving high biodiesel yields with shorter reaction times, even in continuous reactions. This is attributed to reduced energy activation. This method is promising for industrial-scale production of high-quality biodiesel, with methanol as the preferred alcohol.
