| Summary: | The purpose of this research project is to investigate the effects of amount of
catalyst, the ratio of solid to methanol and different temperature on the biodiesel
yield. Solid coconut waste and heterogeneous catalyst derived from the waste, which
is calcium oxide (CaO) are used to produce biodiesel and also examine the kinetics of
the reactive extraction. In this project, the heterogeneous catalyst is produced by
combining solid coconut waste and egg shells and finally treating it with Al2(SO4)3.
Then, the mixture of wastes was calcinated under high temperature. Then, solid
coconut waste in situ transesterification experiment were conducted at different
amount of catalysts (2-6wt%), temperature (50-65°C) and methanol to oil ratio (6:1 –
12:1). The optimum parameters were the solid to methanol ratio, temperature and
mixing speed which were at 1:10, 60 °C and 350 rpm respectively with highest yield of
47 wt%. The result proves that the biodiesel conversion increase with methanol, but
the reaction did not change and decrease after achieving certain percentage of
methanol. |
