Abstract: Biodiesel is one of the alternative energy to replace petroleum
diesel. Biodiesel is produced by transesterification of
vegetable oil into
alkyl ester and
glycerol as by-product. The vegetable oil
based put biodiesel
as a renewable
and environmentally friend
energy source. Research on making of solid catalyst ZrO2/Al2O3
for biodiesel production from jatropha oil has been done. The catalysts were prepared by impregnation
method with different amount of Zr (2,
5, 15, and
20%) and the
components were characterized
by using XRD. Transesterification
reaction was done by reacting jatropha oil with methanol and catalyst with the
ratio of oil to methanol of 1:6, reaction temperature of 60oC, and
reaction time of 3 hours. Biodiesel
produced were analyzed for their yield and composition using GC-MS. The biodiesel products were
also characterized for
their viscosity, density,
acidic and saponification value.
Characterization of catalysts
showed that components
of synthesized ZrO2/Al2O3 were
ZrO, ZrO2, and Al2O3. The highest yield of biodiesel produced was
resulted from transesterification reaction
using catalyst with
2% Zr. GC-MS
results showed that
methyl esters of
biodiesel produced confirmed with
fatty acids in
jatropha oil with
methyl oleic is the highest.
Characteristic of the biodiesel has met the quality standard of ASTM,
prEN and SNI.
