Biodiesel, which is a renewable, biodegradable, nontoxic fuel and similar to diesel fuels, can be used directly for diesel engines. Biodiesel is usually produced by transesterification of vegetable oils and animal fats with alcohols over various catalysts and has received considerable attention for several years. Canola seed is one of the major vegetable oil resources for biodiesel production due to its high oil content. In this work, we investigated a transesterification of
canola oil with methanol in the presence of a immobilized lipase (Novozyme 435). The reaction was conducted under ultrasound-assisted supercritical conditions using carbon dioxide as solvent in a batch reactor. An enzymatic transesterification method of canola oil in ultrasound-assisted supercritical carbon dioxide (SCCO2) has been developed that allows a short reaction time and high yield through enhanced mass transfer in SCCO2 by ultrasonication. The effects
of various parameters such as enzyme loading, methanol to oil molar ratio, reaction time, and ultrasonication power were investigated in this reaction system.
