Abstract
In the present experimental study, an optimization of biodiesel production from different kinds of edible oils (Palm oil, Cotton-seed oil and Sunflower oil) using KOH & NaOH as homogenous catalyst has been investigated by one step transesterification method. The research study was conducted into two parts. In the first experimental study, different types of edible oils (Sunflower oil, Cottonseed oil and Palm oil) have been optimised using KOH and NaOH catalyst for biodiesel synthesis by one step transesterification method. The maximal biodiesel yield (98%) was found by sunflower oil using different reaction parameters such as process temperature of 60°C, Alcohol(methanol) to oil molar ratio [6:1], catalyst (KOH) concentration of 1 gm./100 cc feed and process time of 55 min. In the second experimental study, transesterification reaction parameters were again optimised using optimised feedstock i.e. sunflower oil and optimised catalyst i.e. KOH (homogeneous catalyst) and found the maximal desired biodiesel yield (99%) using a 0.8 gm KOH catalyst, Alcohol (methanol) to oil ratio was 6:1 and 55 minute process time at 55°C. Produced biodiesel properties (Kinematic viscosity, flash point, fire point, cloud point and pour point) were also estimated and confirmed by the biodiesel standard ASTM D6751 and found within the prescribed limit. Gas Chromatography analysis was also performed for checking Fatty Acid Methyl Ester (FAME) purity. These results indicate that KOH as homogeneous catalyst and sunflower oil as edible oil is found to be the best combination of homogeneous catalyst and edible oil in terms of high biodiesel yield with good properties.
