A New Catalyst System in Transesterification of Palm Olein: Tolerance of Water and Free Fatty Acids

Boiler ash (BA) from oil palm empty fruit bunches used as pseudo-homogeneous base catalyst to transesterify palm olein at mild reaction conditions (3 wt.% BA dried at 105 C, 2 h; 15:1 methanol to oil molar ratio at methanol refluxing temperature in 0.5 h) yielded 90% methyl esters. However, the cata...
