Abstract
Abstract: This study investigated the kinetic study of biodiesel from non-edible Jatropha curcas
oil using bentonite clay supported potash from cocoa pod husk as a catalyst in a heterogeneous
catalysis process. The coupled activated biomass (potash) and bentonite clay support was
effective at potash to clay composition of 33.33 wt% and 66.67 wt% (1:2). The coupling was
effective enough to prevent the formation of soap and interference of water molecules during the
reaction. Further characterizations performed showed the presence of active sites on the catalyst.
The highest yield of biodiesel (96.2%) for this study was attained at a temperature of 70 ℃, 10:1
methanol/oil ratio, 10 wt% catalyst loading and time of 75 min. A kinetic study of the
alcoholysis was performed to define the mechanism of reaction. A pseudo-first-order kinetic
reaction was established and the activation energy and frequency factor obtained were 22.03
KJ/mol and 17.28 s-1 respectively.
