Abstract: Nano MgO has been synthesized by hydration and
dehydration method by modifies the commercial MgO. The prepared
MgO had been investigated as a heterogeneous base catalyst for
transesterification process for biodiesel production using palm oil.
TGA, FT-IR and XRD results obtained from this study lie each other
and proved in the formation of nano MgO from decomposition of
Mg(OH)2. This study proved that the prepared nano MgO was a
better base transesterification catalyst compared to commercial MgO.
The nano MgO calcined at 600ºC had gives the highest conversion of
51.3% of palm oil to biodiesel.
