Investigation of solvent system for the production of biodiesel from Sludge Palm Oil (SPO) by enzymatic transesterification
Sludge palm oil (SPO) was used to produce biodiesel by direct enzymatic transesterification using locally produced Candida cylindracea lipases from palm oil mill effluent (POME). The solvent system was investigated by comparing the effect of methanol and ethanol. The yield of biodiesel and co...

| description | Sludge palm oil (SPO) was used to produce biodiesel by direct enzymatic
transesterification using locally produced Candida cylindracea lipases from palm oil mill
effluent (POME). The solvent system was investigated by comparing the effect of methanol
and ethanol. The yield of biodiesel and conversion of free fatty acids (FFAs) into biodiesel
for ethanol were higher than the methanol. Ethanol was selected based on the findings of
ethanol-to-SPO molar ratio, water content, and additional organic solvent. The optimum
ethanol-to-SPO molar ratio was found to be 4:1 while the increasing of water content reduced
the activity of the lipases thus it showed lower yield and conversion of biodiesel. It was also
found that the addition of n-hexane with 1:1 hexane-to-SPO molar ratio increased the yield of
biodiesel and conversion of FFAs by 34.52% and 40.32% respectively. |
