This study was carried out to examine the potential of conversion of rubber seed oil into biodiesel.  A series experiments was conducted using CaO and CaO/SiO₂ as catalyst and coconut oil as co-reactant, with the main purpose to assess the effect of calcination temperatures on the performance of the catalysts. The results obtained demonstrate that the use of coconut oil as co-reactant significantly promoted conversion of fatty acids in rubber seed oil into their corresponding methylesters.  It was also found that the catalytic activity of both CaO and CaO/SiO₂ was significantly influenced by calcination temperatures and at the same temperature, CaO/SiO₂ exhibited higher activity than unsupported CaO.  The highest yield was achieved using CaO/SiO₂catalyst  subjected to calcination at 800 ^oC
