Abstract

Biodiesel production from waste palm oil catalyzed by hierarchical ZSM-5 supported calcium oxide was studied. The acid value, density and kinematic viscosity of palm oil increased after used in frying. Waste palm oil showed a high potential as a feedstock in biodiesel production in which there was no significant different in the conversion of fresh and waste palm oil. In the case of catalyst, it was found that the activity of CaO catalyst increased after supported on hierarchical ZSM-5. h-ZSM-5 could enhance the activity of CaO resulting the increase in conversion from 93.17% to 95.40%. A maximum conversion of 95.40% was obtained at the reaction time of 6 h, the catalyst amount of 3 wt.%, the methanol to oil molar ratio of 12:1 and the reaction temperature of 65 °C. The properties of produced biodiesel required the limits of biodiesel specification according to ASTM D6751-08 and EN 14214 with the methyl ester content of 97.18%, the acid value of 0.24 mg KOH/g, the kinematic viscosity of 4.64 cSt and the density of 869.9 kg/m3. ============================================================ Produksi biodiesel dari minyak kelapa sawit bekas menggunakan katalis CaO berpendukung ZSM-5 hirarki telah dipelajari. Bilangan asam, densitas dan viskositas minyak kelapa sawit meningkat setelah digunakan dalam penggorengan. Minyak kelapa sawit bekas menunjukkan potensi yang besar untuk digunakan dalam produksi biodiesel dimana tidak ada perbedaan yang signifikan terhadap hasil konversi antara minyak kelapa sawit murni dan minyak kelapa sawit bekas. Dari segi katalis, aktifitas CaO meningkat setelah diimpregnasikan dengan h-ZSM-5 sehingga dihasilkan peningkatan konversi dari 93,17% menjadi 95,40%. Maksimum konversi sebesar 95,40% diperoleh dengan waktu reaksi selama 6 jam menggunakan 3 wt.% CaO/h-ZSM-5 dan 12:1 rasio molar methanol terhadap minyak pada suhu 65 °C. Karakteristik biodiesel yang dihasilkan telah diuji dan diperoleh hasil yang sesuai dengan standar ASTM D6751-08 dan EN 14214 dengan kandungan metil ester sebesar 97,18%, bilangan asam sebesar 0,24 mg KOH/g, viskositas sebesar 4,64 cSt dan massa jenis sebesar 869,9 kg/m3.
