This study focuses on optimizing biodiesel production from a refined blend of palm and cottonseed oils, utilizing the MCM-41 nanocatalyst. Palm oil biodiesel is noted for its excellent oxidative stability, but demonstrates poor low-temperature flow properties due to its high-saturated fatty acid content. In contrast, cottonseed oil biodiesel offers enhanced flow properties at low temperatures, but exhibits lower oxidative stability. By blending these two oils, this study aims to maximize biodiesel yield and achieve improved overall fuel properties. The esterification process is optimized using a traditional experimental approach, varying two parameters simultaneously, while maintaining the others constant. The critical variables studied include the molar ratio of alcohol-to-oil, catalyst amount, reaction temperature, and reaction time. The MCM-41 nanocatalyst, a mesoporous silica material with nanoscale features, is selected due to its high surface area, uniform pore distribution, and superior catalytic performance. This methodical approach simplifies the optimization process, reduces experimental complexity, and provides a practical framework for identifying optimal reaction conditions in resource-limited environments.
KEY WORDS: optimization, esterification, transesterification, MCM-41, biodiesel
