Sintesis Katalis Koh/Cao Menggunakan Metode Sol-Gel Untuk Transesterifikasi C…

Biodiesel is an alternative fuel to overcome the problem of limited fossil fuel sources due to increasing use. Biodiesel is synthesized by transesterification of vegetable oil with alcohol and using a catalyst to speed up the reaction. In this study, biodiesel was synthesized using crude palm oil (CPO). The catalyst used was KOH/CaO catalyst derived from blood clamshells (CKD) calcined at 9…
