Abstract

The research of utilitasion of beef tallow into biodiesel with heterogenous (CaO) catalyst has been conducted. Biodiesel production initially by esterification reaction with catalyst H2SO4 1% (toward oil and methanol weight) with molar ratio oil : methanol (1:9). After esterification process, trygliceride separated from methanol and continued by transesterification step with molar ratio 1:12 (oils and methanol) and CaO catalyst 11% wt. Esterification and transesterification process carried out for 2 hours and 6 hours respectively at 65 ℃. Composition of the biodiesel was analyzed by 1HNMR, Gas Chromatography-Mass Spectrometry (GC-MS) and their physical properties analyzed by ASTM method. Result of biodiesel conversion is 93.99% while based on GC-MS analysis showed that mayor component of biodiesel were mixture of methyl esters with methyl octadecanoat as the major coumpound (40.65%). Based on data from ASTM, biodiesel produced from beef tallow have qualified as diesel fuel.
