Abstract
Biodiesel due to its environmental benefits and similar properties with gasoil is considered as fossil fuels alternative. Rapeseed oil is used to produce biodiesel in presence of K2CO3/Al2O3. For catalyst preparation K2CO3 was loaded on the Al2O3 as support using impregnation. Taguchi experimental design was used in a completely randomized design with two replications for trans esterification reaction and investigating the effect of reaction time, temperature and catalyst amount on the biodiesel production efficiency and optimize the number of experiments. Also Molar ratio (alcohol: oil) 15 to 1, catalyst amount 0.5, 1, 1.5, 2, 3 and 5 wt.%, reaction temperature of 55, 65 and 75 °C, reaction time of 0.5, 1, 1.5, 2, 2.5 and 3 hr. and stirring rate of 600 rpm was used for trans esterification reaction. Biodiesel yield (99%) was obtained by trans esterification process at 65 °C using 2 wt. % of K2CO3/Al2O3 in 2 hr. Other researcher’s results comparison shows that the loading ratio of K2CO3 compared to KNO3 and Ca(NO3)2 can increase the biodiesel production efficiency in alumina base catalysts. Analysis of variance analysis with regard to catalyst, reaction time and temperature variables indicates that temperature changes have no significant effect on the efficiency of methyl ester, but the effect of time and amount of catalyst variations used on the conversion rate of the reaction is quite significant.
