    Abstract: A cost-effective green process, simple recovery, and reusability are all facilitated by heterogeneous catalysts. In this research the trans-esterification process was used to produce biodiesel from Carica papaya (pawpaw) and Citrullus lanatus (water melon) seed oil. To compare reaction conditions for biodiesel production with the catalyst (homogene... Show More
