• Abstract: This study focuses on the optimization of the ethyl biodiesel production from macaw palm oil via heterogeneous acid catalyst. H3PMo/Al2O3 catalyst was prepared, characterized and tested for single-step simultaneous esterification and transesterification. A central composite design (CCD) combined with response surface methodology (RSM) was employed to statistically evaluate and optimize the biodiesel production. Effects of variables: reaction temperature (100 - 200 °C), ethanol-to-oil molar ratio (20:1 - 60:1) and catalyst concentration (5 - 15%) on response variables ester content and viscosity were appraised. The variance analysis (ANOVA) indicated that the proposed models are well adjusted and statistically significant. The process achieved an optimum level of 99.8% ester content and 4.1 mm2 s -1 viscosity at 190 °C, 50:1 ethanol-to-oil and catalyst concentration of 13%. The reusability of the catalyst was successfully tested in four subsequent cycles. The fuel properties such as density, monoacylglycerol and diacylglycerol contents were found to be within the limits set by both USA (ASTM D6715) and Brazil (ANP 45/2014) standards.
