- W1991966194 abstract "In this study, biodiesel production from waste cooking oil was investigated. Esterification and transesterification reactions were carried out under microwave irradiation using heterogeneous (Amberlyst-15) and homogeneous (KOH) catalysts, respectively. The acidity of the oil was reduced from 6.92 to 1.09 mg KOH/g by an esterification reaction to avoid saponification during the transesterification reaction. Optimum esterification reaction conditions were investigated as 75°C, catalyst ratio of 25 wt % Amberlyst-15, 30 min, a 1:12 WCO:methanol molar ratio and stepwise methanol addition. The energy consumption of the biodiesel production under microwave heating was calculated and compared with a conventional heating system. The transesterification reaction was performed at 65°C for 3 min, at a 1:7 oil:methanol molar ratio, and 1 wt % KOH. The methyl ester content of the biodiesel was increased from 25.06% to 97.23% when an esterification reaction was applied prior to transesterification. © 2014 American Institute of Chemical Engineers Environ Prog, 34: 575–581, 2015" @default.
