PhD Oral Defense: Influence of ultrasonic mixing on enzyme catalyzed biodiesel production from waste animal fats

PhD Oral Defense of Peter Adewale, Department of Bioresource Engineering

This study investigated the influence of ultrasonic mixing on enzyme catalyzed biodiesel production from waste animal fats. Non-edible feedstocks such as animal fat wastes (AFW) have recently increased in popularity as alternatives to vegetable oils in the production of biodiesel. They are low cost, mitigate environmental damage and increase the quality of the resultant biodiesel fuel (low NOx emissions, high cetane number and oxidative stability). But the presence of a high content in free fatty acid (FFA) in AFW has been seen as a challenge, especially when synthesized by alkaline-catalyzed transesterification.
