Optimization of palm oil biodiesel production using response surface methodology

The purpose of this paper was to analyze palm oil biodiesel production under different conditions and verify the relationships between variables in order optimize biofuel using response surface methodology (RSM). Biodiesel produced through transesterification process by methyl route alkali catalyst (NaOH) 1% (m/m). analyzed were: four molar ratios (3:1, 4:1, 6:1 8:1); three temperature reactions (45°, 52° 60°C); time (40, 60 80 minutes). For production, highest yield 93%, obtained via a rate 3:1, 52°C minutes. This result differs from previous studies that found higher with ratio increases, implying greater expenses methanol. Kinetic viscosity specific mass were also analyzed, values are within Brazilian, American, European standards. results showed most influent factor rate. In relation characterization, RMN H1 technique, it possible obtain reaction 79.50% for 3:1 biodiesel. Through gas chromatography, can be verified predominant fatty acids samples palmitic oleic acids.
