Abstract

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/SiO2 catalyst subjected to calcination at 800 oC
