The effects of methanol to oil ratio, reaction temperature, the amount of NaOH catalyst, and stirred speed on the transesterification yield of the biodiesel have been examined. The purpose of this study was to investigate the optimization production of operated parameters for this fluid-bed reactor. This research investigated the influence of the biodiesel yields on the reaction parameters, methanol to oil ratio in the range of 3:1 to 6:1, reaction temperature in the range of 50 to 70oC, amount of catalyst in the range of 0.3 to 0.7wt%, and surface velocity in the range of 50 to 250 cm/min. The results showed that the biodiesel yield increased with an increase in the ration of methanol to oil ratio of 3:1 to 6:1. The biodiesel yield decreased with an increase in the amount of NaOH catalyst. The biodiesel yield was not significantly effect on the surface velociety. Moreover, the optimal yield of biodiedel could be maintained 97% under MeOH/oil ratio of 4:1, the reaction temperature of 60°C, the amount of catalyst concentration was 0.6wt%, and surface velocity at 125 cm/min. The module of oxidation stability of biodeiesel and its applicability were also investigated in this study. The test parameter included oxidation temperature, gas velocity, biodiesel amount in the degradation bottle, stir velocity and water amount in the gas absorption bottle. As a result had shown that the soybean biodiesel could be inspected effectively from homemade and industry biodiesel.
