A Review Paper on Biodiesel Production via Non Catalytic Supercritical Alcohol

Abstract

This paper reviews the production of Biodiesel using supercritical alcohol. Biodiesel is an attractive alternative fuel because it is environmentally friendly and can be synthesized from edible and non-edible oils. Biodiesel is made from renewable biological sources such as vegetable oils and animal fats by non-catalytic supercritical alcohol transesterification methods. A noncatalytic Biodiesel production route with supercritical methanol has been developed that allows a simple process and high yield within short reaction time because of simultaneous transesterification of triglycerides and methyl esterification of fatty acids.
