ABSTRAK
Kemiri Sunan adalah sumber energi alternatif yang mempunyai kadar minyak yang cukup banyak dan tidak dikonsumsi oleh manusia. Hydroprocessing minyak nabati kemiri sunan berpotensi menghasilkan bahan bakar terbarukan. Penggunaan katalis NiMoCe/?-Al2O3 diharapkan bisa menggantikan katalis NiMo/?-Al2O3 tersulfidasi dalam hydroprocessing minyak kemiri sunan dan diharapkan akan menghasilkan konversi hidrokarbon terbarukan. Katalis dipreparasi menggunakan metoda impregnasi basah dengan variasi Ce 1 , 5 dan 15 . Karakterisasi katalis dilakukan dengan teknik BET, SEM, XRD dan XRF. Hydroprocessing dilakukan dengan menggunakan autoclave batch reactor dengan kondisi operasi suhu 400oC dan tekanan 35 bar selama 5 jam. Hasil konversi minyak kemiri sunan berdasarkan karakterisasi GC menghasilkan hidrokarbon terbarukan yang didominasi oleh rantai alkana C15-C18. Syncrude hasil hydroprocessing kemiri sunan dengan katalis NiMoCe/?-Al2O3 1 memberikan hasil konversi bahan bakar terbarukan berupa fraksi diesel sebesar 57.79 . Hasil analisis terhadap fraksi diesel terbarukan hasil distilasi syncrude menunjukkan bahwa fraksi diesel terbarukan memenuhi standar baku mutu yang dipersyaratkan oleh Direktorat Jenderal Minyak dan Gas Bumi.

ABSTRACT
Kemiri Sunan is an alternative energy source that has a considerable amount of oil and is not to be consumed by human. Hydroprocessing of kemiri sunan oil has the potential to be produced as renewable fuels. The NiMoCe Al2O3 catalysts has the potential to replace sulfided NiMo Al2O3 catalysts in hydroprocessing of saturated kemiri sunan oil and is expected to convert it to be renewable hydrocarbons. The catalyst was prepared by using wet impregnation method with variations of Ce 1 , 5 and 15 . Characterization of the catalyst was performed by BET, SEM, XRD and XRF techniques. Hydroprocessing was performed using an autoclave batch reactor under operating conditions of 400 C and 35 bar pressure for 5 hours. The result of the conversion shown based on GC characterization produces renewable hydrocarbons dominated by the C15 C18 alkana chain. Syncrude of kemiri sunan oil hydroprocessing by using NiMoCe Al2O3 1 produces diesel fraction conversion which is 57.79 . Analysis result of the renewable diesel fraction of the syncrude indicate that the renewable diesel fraction qualify the goverment standard required
