TRANSESTERIFICATION OF JATROPHA CURCAS OIL WITH METHANOL

ABSTRACT

This aim of this project is to investigate the conversion of Jatropha curcas seed oil into biodiesel using methanol with sodium hydroxide as a homogeneous catalyst. The primary objective is to assess the feasibility and productivity of biodiesel production from Jatropha curcas oil, recognizing its promise as a sustainable and renewable energy alternative. In pursuit of advancing the realm of biodiesel manufacturing and renewable energy sources, this research endeavours to refine reaction parameters and evaluate the specifications of the resultant biodiesel. To perform transesterification reactions of Jatropha curcas seed oil with methanol in the presence of sodium hydroxide catalyst, the study used a mixing and stirring technique. The following raw ingredients were acquired and processed in accordance with known protocols: sodium hydroxide, methanol, and Jatropha curcas seed oil. The catalyst concentration, an important reaction variable was varied during transesterification processes. The procedure was closely watched, and samples were taken for examination on a regular basis. The study's findings show that transesterification of Jatropha curcas seed oil with methanol utilizing sodium hydroxide as a catalyst produced viable results. Implementation of reaction conditions led to improved yield and quality of biodiesel 87%, with parameters including a molar ratio of 6:1, reaction temperature of 55oC, and catalyst concentration of 0.4wt%. Analysis of the produced biodiesel revealed favourable properties in terms of viscosity, acid value, flash point and cloud point meeting international standard for biodiesel.
