A sustainable way of producing biodiesel using microwave technique

Farid Nasir A., . and Farough M., . (2014) A sustainable way of producing biodiesel using microwave technique. [Proceedings Paper]

As the global economy grow depleting the supply of petroleum resources with global warming issues and increasing prices of petroleum in the present time motivated scientists to search for new alternative and cheap energy resources. Utilization of edible and non-edible oils for biodiesel using conventional processing technique is costly due the application of electrical or steam energy. In this study a comparison was made using conventional method and microwave irradiation method of production of biodiesel looking at different microwave powers reaction time and reaction temperatures. The waste cooking oil WCO methyl ester was used as reference for this work. The effect of critical parameters including reaction temperature microwave exit power stirrer speed and reaction time were investigated. The results showed that microwave assisted irradiation is one of the best methods to reduce the reaction time and separation time as well. It showed that microwave irradiation decreases the reaction time dramatically from using conventional methods of 60 to 180 min to only 5 to 9 min. The physical properties of WCO methyl ester also met most of the biodiesel standards around the world. Characterization was done according to the ASTM method and was compared with published data. The processing specific energy was obtained using this technique and proves that it is sustainable. Thus continuous processing of biodiesel using microwave technique proves to be a sustainable way to produce biodiesel.

Abstract

As the global economy grow depleting the supply of petroleum resources with global warming issues and increasing prices of petroleum in the present time motivated scientists to search for new alternative and cheap energy resources. Utilization of edible and non-edible oils for biodiesel using conventional processing technique is costly due the application of electrical or steam energy. In this study a comparison was made using conventional method and microwave irradiation method of production of biodiesel looking at different microwave powers reaction time and reaction temperatures. The waste cooking oil WCO methyl ester was used as reference for this work. The effect of critical parameters including reaction temperature microwave exit power stirrer speed and reaction time were investigated. The results showed that microwave assisted irradiation is one of the best methods to reduce the reaction time and separation time as well. It showed that microwave irradiation decreases the reaction time dramatically from using conventional methods of 60 to 180 min to only 5 to 9 min. The physical properties of WCO methyl ester also met most of the biodiesel standards around the world. Characterization was done according to the ASTM method and was compared with published data. The processing specific energy was obtained using this technique and proves that it is sustainable. Thus continuous processing of biodiesel using microwave technique proves to be a sustainable way to produce biodiesel.
