 Production of biodiesel from waste cooking oil using a homogeneous catalyst: Study of semi-industrial pilot of microreactorMajid Mohadesi, Babak Aghel, Mahmoud Maleki and Ahmadreza Ansari Renewable Energy, 2019, vol. 136, issue C, 677-682 Abstract: This study investigated the transesterification of waste cooking oil (WCO) with methanol in the presence of potassium hydroxide as the catalyst. A semi-industrial pilot of microreactor with 50 tubes with a diameter of 0.8 mm was used to produce 5 L/h biodiesel. Initially, the acidity of waste cooking oil was reduced to less than 1 mg KOH/g oil by using methanol at 60 °C in the presence of 1% sulfuric acid. Using Box-Behnken design method, the effects of methanol to oil molar ratio (6:1–12:1), catalyst weight (0.5–1.5 wt %), and reaction temperature (55–65 °C) were studied. The methanol to oil molar ratio of 9.4:1, the catalyst concentration of 1.16 wt %, and the reaction temperature of 62.4 °C was achieved under optimum condition. Finally, the effect of reaction time (30–120 s) was examined at the optimum condition. The highest level of biodiesel purity or fatty acid methyl esters % (FAMEs %) was 98.26%. In addition, the properties of produced biodiesel were determined and compared with those of the standard ASTM D6751.
