Abstract

Petrol with a lot of used to the car somedays it will run out and limit to use and biodiesel will be the substitute to the petrol to be the fuel of the car. An experimental investigation were conducted to know the effect of biodiesel production based on zinc oxide support by silica oxide. The use of heterogenous catalyst by wet impregnation method was performed with the different percentage weight over weight of catalyst with differents temperature of calcination to make a high quality green biodiesel. Catalyst characterization which are XRD and SEM were conducted in this experiment to check the zinc oxide and silica oxide exist in the catalyst. Transesterification process were performed using the waste cooking oil (WCO) as a main feedstock to determine the acid value and free fatty acid of each of the catalyst. The results are using 5% percentages weight over weight of the zinc oxide supported by silica oxide will produce lowest acid value and free fatty acid.
