Biodiesel from Sesame oil: Base catalysed transesterification
About this article
Abstract
A process for the production of methyl ester from Sesame oil containing 6.1% free fatty acid (FFA) for the use as a biodiesel was studied. These studies were carried out on transesterification reaction of Sesame oil with methanol to produce biodiesel. The reaction parameters such as Methanol/Oil molar ratio, catalyst concentration and reaction time were optimized for the production of sesame oil methyl ester (SOME). Conversion of triglyceride has been monitored from viscosity measurement and also by measuring produced glycerin concentration. Pseudo first order kinetic model has been proposed for the transesterification of Sesame oil to biodiesel and the data are fitted with the model to evaluate the kinetic parameters. Biodiesel properties such as cetane number, kinematic viscosity, flash point, pour point, cloud point are measured and compared with biodiesel and petro-diesel standard.
