Abstract
Biofuel is an alternative energy product that is environmentally friendly. Biofuel production is one of resolving the problems of energy shortage and global warming. This research aims to study the process of biofuel production from candlenut oil. The research was carried out by reacting the candlenut oil in a micro fixed bed reactor with diameter of 1 cm and length of 16.4 cm. Catalytic cracking method with Zn/HZSM-5 catalyst was used in this process. The effect of reactor temperature and nitrogen flow rate on the quality of biofuel was studied. Biofuel products were analyzed using Gas Chromatography. Biofuel composition is obtained by comparing the chromatogram of biofuels to the standart chromatogram. The result proves that biodiesel was the highest fraction of biofuels. The highest percentage of biodiesel was 80.75 % at a temperature of 325 °C and a nitrogen flow rate of 60 ml/min. Biofuel density was in the range of 0.81 to 0.84 g/ml. This biofuel had a cetane number of 74.8. Biofuel had octane number of 124.7, 114.7, and 119.7 using RON, MON, and AKI methods respectively. Biofuel had higher heating value of 19.269 btu/lb. Cetane number of biofuel was 46, 7% greater than that of fuel European Standard EN 590. This product can be recommended as a cetane improver.
