Biodiesel: Waste Vegetable Oil Energy

Abstract

This paper presents a non-thermal transesterification process for making biodiesel to reduce an energy production cost. From the experiments found that yield of methyl ester or biodiesel is equal to 70-80%, meaning for, one liter of waste vegetable oil can transfer to 735ml of biodiesel. The characteristics of biodiesel from the experiments are qualified according to the standard announced by The Department of Energy Business, Ministry of Energy. From present data, although yields of methyl ester form non-thermal transesterification process is lower than thermal transesterification process In the future, if the production cost of biodiesel from thermal transesterification is still rising up and yet no method could be used for cost reduction. The nonthermal transesterification process is the appropriate choice especially for household used for an agriculture engines.
