| Biodiesel is a major renewable energy source derived from vegetable oils. Modern techniques are now required to produce biofuels, particularly biodiesel, to improve the process’s efficiency and sustainability due to technological advancements. This study focuses on continuous biodiesel production from waste cooking oil through transesterification in a flow process with microwave heating. Calcium oxide prepared from willow leaves extract was used as a catalyst at concentrations ranging from 1% to 4%, with a microwave power of 20% from a total 800W and an irradiation time of 0.5-7 min. The oil-to-methanol ratio was 50wt.%-80wt.% and reaction temperature of 45-75℃. The results reviled 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, which followed ASTM standard specifications, was facilitated by all operational conditions. The results suggest that microwave heating is a viable approach for achieving high yields of biodiesel with shorter reaction times, even in continuous reactions. This is attributed to reduced energy activation. This method is promising for industrial use in the production of high-quality biodiesel, with methanol as the preferred alcohol. | ||
