ABSTRACT

Elevated economic and environmental concerns have spurred the exploration of vegetable oils for biodiesel production, offering a greener alternative to conventional fossil diesel. With inherent fatty acid content vital for yield enhancement, this research delves into the kinetics of fatty acid esterification within a blend of (palm/cotton) oil. The investigation encompasses varied methanol molar ratios at different temperatures, Employing sulfuric acid as a catalyst with concentrations precisely designated at 5 wt% and 10 wt%. Optimal conditions include a methanol-to-oil molar ratio of 3:1, a 10% catalyst concentration, and a temperature of 60°C, resulting in a more efficient reaction time. Furthermore, This study rigorously evaluated physical and chemical properties, including acid value, FFA%, viscosity, and density, for both the oil blend and each of its components. A proposed kinetic model, employing the initial rates method, determined a rate constant of (2.3×10^(-3) Lit/mol.min) for the direct esterification reaction. Exploration of temperature's impact on the rate constant, utilizing the Arrhenius equation, revealed an activation energy (Ea) of 95.7357 kJ/mol. These comprehensive findings not only optimize the biodiesel production process but also underscore the importance of sustainable practices in shaping a cleaner and more efficient energy landscape.
