Synthesis of Biodiesel from Jatropha curcas Seed Oil Using CaTiO۳ Catalyst and Optimization of Process Parameters to Improve the Biodiesel Conversation

Long-chain fatty acid monoalkyl esters are the main component of biodiesel. It is created through the transesterification of animal fats, non-edible oils, and edible oils using an acid or base catalyst and ethanol or methanol. In this study, n-hexane was used to extract the oil. A central composite design (CCD) and response surface methodology (RSM) approach were used to maximize the generation of biodiesel from seed oil. Transesterifying Jatropha seed coil with ۰.۳۰ g of catalysts and ethanol to oil molar ratio of ۱۰.۵۰ at ۶۵ oC for ۳.۶۸ hrs. resulted in an optimal biodiesel yield of ۹۸.۵۰%. With a low percentage error (۰.۸۸%), the experimental yield and the projected yield correspond well. This demonstrates that the suggested statistical model is appropriate for forecasting the optimal biodiesel yield and for optimization of the transesterification process.
