In this study, the potential of limestone based catalyst on microwave
assisted closed heating transesterification of Malaysian rubber seed oil (RSO)
which is rich in high Free Fatty Acid (FFA) was investigated. The experimental
results showed that the conversion of high FFA oil to biodiesel is very efficient
compared to various catalysts. The catalytic activity is not negatively affected by
the free fatty acids and can be recycled very easily. Brunauer–Emmett–Teller
(BET) analysis was also used to find the surface area of the catalyst at each cycle.
The highest conversion achieved was 96.80% with catalyst concentration of 6
wt%; methanol to oil molar ratio of 5:1; reaction temperature of 60°C and reaction
time of 60 minutes. The biodiesel produced is within the limits being prescribed
by ASTM D 6751.
