cepacia lipase immobilized on cellulosic polyurethane
was used as a catalyst
for biodiesel production via trans-esterification reactions in order
to provide cost-effective methods of enzyme recycling. The efficacy
of the immobilized enzyme catalyst at low loading (6.2 wt %) and the
effects of temperature, water content, and reaction time in model
trans-esterification of glyceryl trioctanoate were investigated extensively.
It was found that water was necessary for the reaction of glyceryl
trioctanoate with ethanol to proceed. A high conversion of glyceryl
trioctanoate (∼70%) was obtained at 35 °C, with only 5.0
wt % of water content over a reaction period of 12 h.
