Abstract:
Biodiesel represents a suitable alternative to the petroleum-derived diesel fuel as it is
renewable and can be used directly in compression-ignition engines. Present work was aimed at
extraction of cantaloupe seed oil and its application to the production of biodiesel through basecatalyzed transesterification using four different basic catalysts viz. NaOH, NaOCH3, KOH and
KOCH3. The percent yield of biodiesel afforded by these catalysts was 94.5, 88.0, 85.5 and 89.5%,
respectively. The results indicated that NaOH was the best catalyst for transesterification of cantaloupe
seed oil. Further, optimization of the process variable, including methanol to oil mole ratio, reaction
temperature and amount of catalyst (NaOH) was carried out. The optimum levels of these variables
that afforded maximum biodiesel yield were found to be 6:1 molar ratio of methanol to oil, 60 oC
reaction temperature and one percent wt/wt catalyst loading. From the results obtained in this study,it
was concluded that cantaloupe seed oil can be successfully utilized for the production of biodiesel as a
cost-effective feedstock
