Crude palm kernel oil transesterification
Table 2 summarizes the methyl esters content and yield from
the crude palm kernel oil transesterification with the prepared
solid catalysts. Run 1 shows that, if there is no catalyst, the purity
and amount of methyl esters is relatively low, even if the reaction
is performed at high temperature (200 ◦C) with a long reaction
time (4 h). However, when the solid catalysts are added, the
methyl esters content and yield in the product are significantly
increased. This indicates that the solid catalysts considerably
increase the level of the transesterification of crude palm kernel
oil.
