This study focuses on the optimization of the ethyl biodiesel productionfrom macaw palm oil via heterogeneous acid catalyst. H3PMo/Al2O3 catalyst wasprepared, characterized and tested for single-step simultaneous esterification andtransesterification. A central composite design (CCD) combined with response surfacemethodology (RSM) was employed to statistically evaluate and optimize the biodieselproduction. Effects of variables: reaction temperature (100 - 200 °C), ethanol-to-oilmolar ratio (20:1 - 60:1) and catalyst concentration (5 - 15%) on response variablesester content and viscosity were appraised. The variance analysis (ANOVA) indicatedthat the proposed models are well adjusted and statistically significant. The processachieved an optimum level of 99.8% ester content and 4.1 mm2s-1viscosity at 190 °C,50:1 ethanol-to-oil and catalyst concentration of 13%. The reusability of the catalystwas successfully tested in four subsequent cycles. The fuel properties such as density,monoacylglycerol and diacylglycerol contents were found to be within the limits set byboth USA (ASTM D6715) and Brazil (ANP 45/2014) standards.
