 Oil&description=Biodiesel is another form of renewable energy with various applications. In this context, biodiesel characterization showed that kinematic viscosity at 40°C was 5.3, cetane number was 68.1, flash point 240, pour point was -12, density was 0.85, specific gravity was 0.85, sulfated ash was 0.6, copper strip corrosion test was 1b and the high heating value was 42.4. The empirical model obtained showed that reaction time, catalyst concentration and reaction temperature are the most important variables that influence the process. Irrespective of the amount of methanol employed, biodiesel yields in excess of 69% were obtained only when the trans-esterification taken place at temperature of 65°C for 74 mins. The optimal process condition was discovered to be when the temperature, reaction time and catalyst concentration were 66.26°C, 74.4 minutes and 5.23 M, respectively. Validation results (68.7 ± 0.8%) are generally in agreement with the predicted value of 70.04%.&picture=http://www.aascit.org/aascit/decorators/img/journal/975.jpg)
