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.
