SINTESIS METIL ESTER DARI MINYAK DEDAK PADI MENGGUNAKAN KATALIS KALIUM DENGAN PENGEMBAN ZEOLIT ALAM
ABSTRACT: Biodiesel is an
alternative renewable energy source having many advantages such as environmental
friendly, non-toxic, and has lower emission gases. Biodiesel is produced fromtransesterification
of vegetable oils or animal fat. In this research, the transesterification of
rice barnoil (RBO) using the solid base catalyst was studied. The performances
of the catalysts were evaluated in terms of the reaction temperatures, the
molar ratios of methanol to oil, and the catalyst loading. The effects of the
mass ratio of catalyst to oil (1-10%), the molar ratio of methanol to oil
(6:1-12:1), and the reaction temperature (40-60 oC) were studied for the yield
of biodiesel to optimize the reaction conditions. The results showed that the
optimal conditions were a methanol to oil molar ratio of 12:1,the amount of
catalyst of 10%wt. of oil, and reaction temperature of 60 oC. The
physicocharacteristics of the catalysts were analyzed by Nitrogen gas adsorption,
surface functional groups by Fourier transform infrared spectroscopy (FT-IR),
X-Ray Fluorescence Spectroscopy (XRF), and XRay Diffraction (XRD).
