Production of Biodiesel from Chicken Frying Oil

Abstract

Chicken fried oil was converted into different biodiesels through single step transesterification and two step transesterification, namely acid-base and base–base catalyzed transesterification. Hydrochloric acid and potassium hydroxide with methanol were used for this purpose. The results showed that two step base catalyzed transesterification was better compared to other methods. It resulted in higher yield and better fuel properties. Transesterification of fried chicken oil was monitored by TLC technique and compared with that of the parent oil. Fuel properties of the products have been measured and found markedly enhanced compared to those of the parent oil. Also, the values satisfied the standard limits according to the ASTM standards. Blending of the better biodiesel sample with petro diesel was made using three volume percentages (10, 30 and 50% v/v). The results disclosed that blending had slight effect on the original properties of petro diesel.
