Biodiesel is a type of liquid biofuel produced from renewable sources such as oils and fats and can be used as a replacement for fossil diesel in diesel engines. It emits far less pollutants than standard diesel fuel. In this study, the effect of two parameters of catalyst concentration and reaction time on the conversion rate of microalgae oil transesterification reaction at three levels was investigated by response surface methodology. The results of three-dimensional graph analysis using Minitab software showed that the highest biodiesel production from microalgae oil was obtained at 1.2% (w/w) catalyst concentration and 60 min reaction time. Under these conditions, the conversion rate of microalgae oil to biodiesel was 77.85% and also according to GC-MS analysis the reaction conversion to methyl ester was over 90%. Comparison of the biodiesel combustion heat obtained (40.2 j/g) with other jet fuels indicates that the resulting biodiesel performance is very close to the JP-4 fuel.
