FAME yield after 3 h. The transesterification activity was faster with increasing reaction temperature.
The reactions performed at 65 and 75 C demonstrated similar catalytic profiles for which biodiesel yields could be obtained at more than 93% after 30 min.
Thus, the reaction temperature of 65 C appears to be an appropriate temperature for the transesterification between soybean oil and methanol with 0.10Sr/MgO(600)catalyst.
