Biodiesel is becoming an area of high concern because of high petroleum prices, increasing environmental concerns and the fact that it comes from renewable resources. It is a natural substitute for petroleum-derived diesel fuel consisting of the alkyl monoesters of fatty acids from vegetable oils of animal fats. Biodiesel is industrially produced by transesterification of riglycerides with short chain alcohols over various catalysts. Canola oil is one of the major vegetable oil resources for biodiesel production due to its high oil content. In this study, the transesterificaion reaction of canola oil with methanol in the presence of a novozym 435 (immobilized lipase) was investigated using supercritical carbon dioxide as a solvent. The reaction was conducted under ultrasound-assisted supercritical conditions in a batch reactor. Various parameters such as temperature, catalyst concentration, ultrasonication power, supercritical carbon dioxide density, oil to methanol ratio, amount of oil, and reaction time were investigated in order to evaluate the feasibility of converting canola oil to biodiesel.
