Biodiesel is one of the alternatives to petroleum fuel and it can be produced through transesterification of vegetable oil, animal fats and recycle greases with methanol in the presence of a catalyst. The main ponent of biodiesel is fatty acid methyl esters. Biodiesel has many advantages: low viscosity, high flash point, high cetane number, nontoxic and biodegradable, and it can reduce greenhouse gases release to the atmosphere during the utilization. It is of a great significance for solving the global warming problem and reduction of acid rain, protecting environment and achieving sustainable economic development. In this study, seed oil was used as the feedstock. The main subject of this study is divided into three parts: The first, the parameters of the production of biodiesel was settled as below: the molar ratios of methanol to oil is in the range of 4: 1 ~ 12:1, quantity of acid catalyst is in the range of 4wt% ~ 12wt%, reaction temperature is in the range of 60℃ ~ 80℃ and reaction time ranges from 90min ~ 180min. The second, 13 experiments were designed by the single factor method to determine the optimal parameters. After 180min reaction, acid values of reacted mixture were detected and the results showed that the optimal conditions of biodiesel production are: molar ratios of methanol to oil, 9:1。 loaded acid catalyst, 6wt%。 reaction temperature, 65℃ . The last, based on the above results, 13 experiments were obtained by BOXBehnken design and results showed that the the optimal conditions of biodiesel production are: molar ratios of methanol to oil, :1。 loaded acid catalyst, 4wt%。 reaction temperature, ℃ 。 reaction time, 60min.
