Abstract
Development of biodiesel production process is one of the efforts to overcome energy crisis of fuel consumption derived from crude oil, mainly diesel fuel for transportation and industry that increases annually. The crude oil is predicted will diminish within twenty years, therefore vegetable or animal oils are promisingly resource for the production of biodiesel. In the research, biodiesel was produced using CaO as heterogeneous catalyst through transesterification process. The heterogeneous catalyst had more advantages than the homogeneous one since it was not corrosive to metal and polluted to biodiesel and glycerol being produced. The heterogeneous catalyst was easily separated from the liquid product and it could be designed to possess higher activity and selectivity, as well as, longer lifetime. The aim of the research was to determine the optimum operating condition of the transesterification of coconut palm oil and methanol using CaO as the heterogeneous catalyst to produce biodiesel as main product and glycerol as by product. The process variables included the ratio of coconut palm oil to methanol, R = 1:6 ad 1:8; reaction time, t = 0,5 to 3,0 hours and catalyst weight ratios, w = 4 to 12 %. The process was conducted in 500 ml glass reactor completed by agitated heater, thermometer and reflux condenser. Samples were taken at every 0.5 hours, and the glycerol formed and conversion was calculated. The experimental results showed that conversion of coconut palm oil increased along the reactant ratios, reaction time, and catalyst weight ratios. The reaction rate constant, k increased with the increase of the catalyst weight ratios. The highest conversion of 96.24 % was achieved at reactant ratio of 1:8, catalyst weight ratio of 12 % and reactant time of 3,0 hours at temperature of 65 oC while the highest k values of 2.16 x10-2 min-1 was achieved at reactant ratio of 1:6 and the catalyst weight of 12 %.
