| description | Diminishing reserves of fossil fuels and arising of food crisis recently have
drawn attention for researchers to produce an alternative fuels. Biodiesel which is
made from vegetable oils, animal fats or microbial oils is one of the attractive
alternative fuels due to this concern. Other than that, biodiesel is an environmental
friendly fuel which emitted less greenhouse effect gas. Cerbera odollam oil was
determined as a non-edible feedstock for biodiesel production. The enzymatic
transesterification of Cerbera odollam oil as a feedstock has been studied in the
present research.
Cerbera odollam oil has been extracted using n-hexane solvent in a soxhlet
extractor. The enzymatic transesterification were carried out in a batch system to
screen the most efficient enzyme among Lipozyme RM IM, Lipozyme TL IM and
Novozyme 435 based on the highest fatty acid methyl ester (FAME) yield in the
process. The best organic solvent used in this reaction was also determined in a batch
process between tert-butanol and n-hexane to eliminate the inhibition of methanol in
the reaction. Important parameters like temperature, speed agitation, enzyme
concentration, methanol to oil ratio and solvent to oil ratio in enzymatic
transesterification reaction were optimized by using response surface methodology
(RSM) based on central composite design (CCD). The kinetic studies of enzymatic
tansesterification were carried out in this research. Enzymatic transesterification of
Cerbera odollam oil reaction was also studied in a packed bed reactor (PBR) for a
continuous process. The effect of mass transfer in the PBR was also studied. |
