For biodiesel to be used in diesel engines, the fuel must meet
various specifications stated in biodiesel standard, mainly United
States biodiesel standard ASTM D6751 and European biodiesel
standard EN14214. The fuel properties of Jatropha-based biodiesel
from CaOeLa2O3 catalyzed reaction was summarized in Table 7
along with a comparison to the recommended biodiesel international
standards EN14121 and ASTM D6751. The physico-chemical
properties assessed includes, density, kinematic viscosity (40 C),
flash point, pour point, sulfated ash, acid value, iodine value and
moisture content. The results revealed comparable properties of
jatropha-based biodiesel with fossil diesel, which affirm the suitability
of high acidity J. curcas oil to be a biodiesel feedstock if
bifunctional acidebase CaOeLa2O3 is use as transesterification
catalyst.
