Determining the Characteristics of Biodiesel from a Mixture of Crop Mustard and Edible Waste Oil using heterogeneous Calcium Oxide Catalyst Prepared from Fish bones and Predicting the Efficiency of Biodiesel using Taguchi Statistical Program Model

In this study, in order to produce biodiesel fuel from mixture of crop mustard and edible waste oil, ester exchange method with heterogeneous calcium oxide catalyst prepared from fish bones was used as a catalyst. Then, the effect of the contribution of important and effective factors on the molar ratio of oil to methanol, catalyst percentage, reaction temperature and reaction time on the amount of biodiesel production was investigated using Taguchi experiment design method. In biodiesel production method the optimum reaction, it can be seen that the effect of this parameter is strongly effective in the production of biodiesel with a ratio of (1:12), that this molar ratio of oil to methanol (1:12) has the best efficiency. According to the results, the amount of (0.3%) calcium oxide catalyst prepared from fish bones can be considered as the maximum value in biodiesel production. It was observed that, with increasing the reaction temperature from (55°C to 65°C), the amount of biodiesel production increases by about 8% and with the continuation of increasing the temperature from (65°C to 75°C), with a sharp decrease in production (about 30%) We face. As a result, temperature for biodiesel production is (65°C), and best efficiency and maximum percentage of biodiesel production occur in (5 h) of reaction time. The thermophysical properties of biodiesel produced from these oils were compared with standard biodiesel and all its properties were within the allowable range of standard ASTM D-6751.
