This research work is study the catalytic cracking of tung oil on heterogeneous base catalyst in a batch microreactor of 250 ml. The experiment was carried out under the various condition by the following variable: reaction temperature ranging 390°C to 440°C, reaction time of 30 to 60 minute, initial hydrogen pressure of 1 to 5 bars and amount of catalyst ranging from 2.5 to 10% by weight. The two level factorial experimental design was perform to investigate the effect of variable of oil yield to optimum condition. The product oil was analyzed by Simulated Distillation Gas Chromatography (DGC). According to design-expert program, it was found that reaction of tung oil on calcium oxide catalyst is temperature of 440°C, reaction time of reaction 38 minute, initial hydrogen pressure 1 bars by using 2.5 percent by weight gave the highest yield. The oil yield was 37.55 percent by weight, the naphtha yield was 19.16 percent by weight. In the reaction of tung oil on Magnesium oxide catalyst is temperature of 402°C, reaction time 30 minute, initial hydrogen pressure 1 bars by using 2.5 percent by weight gave the highest yield. The oil yield was 38.83 percent by weight, the naphtha yield was 21.43 percent by weight.
