Soybean oil, palm oil and waste cooking oil as feedstock were used to measure the effects of different heating methods, reaction time, molar ratio of methanol to oil, temperature, power, catalyst type and catalyst concentration on the biodiesel yield in this study. Additionally, reducing reaction time for the transesterification reaction used microwave heating to make more complete.
The optimized operating conditions of conventional heating used palm oil, concentration for 0.75 wt% sodium methoxide, molar ratio of methanol to oil for 6:1, reaction time for 90 min and reaction temperature for 60 ¢J offered the best yield of 98.1%. the microwave heating used palm oil, concentration for 0.75 wt% sodium methoxide, molar ratio of methanol to oil for 6:1, reaction time for 3 min and power for 750 W offered the best yield of 99.5%
Used soybean oil and palm oil as biodiesel feedstock production, its yield was higher than the waste cooking oil. This reason is caused by composition complex and high viscosity of waste cooking oil compare with pure vegetable oil. The catalyst of sodium methoxide is higher effective than sodium oxide used in transesterification reaction, because the reaction process will not formation of water and saponification. Use ionic liquid [Pyr12CN][Cl], [MorEtH][HSO4], [MorMeMe][MeSO4], [PyrMeH][HSO4] and [MorMeEt][EtSO4] as biodiesel catalyst, the optimized operating conditions of concentration for 2.00 wt% [Pyr12CN][Cl], molar ratio of methanol to oil for 6:1, reaction time for 6 min and power for 750 W offered the best yield of 98.1%.
