2、o it has been already paid attention to，especially in western developed countries where it has been a commercial stuff. Generally, bio-diesel comes from transesterification of animal grease or plant oil with alcohols. Th

3、e characteristics of bio-diesel are very similar to those of diesel fuel. Therefore, bio-diesel can be used immediately in diesel engines without changing the structure of the engines. It is an unique fuel oil that is up

4、 to the standard of exhaust emission of strict Europe No.3. It is very practical to utilize bio-diesel in China, which close associates with petroleum safety, national economy, environmental protection and readjustment o

5、f agriculture structure in China. The thesis that provides the foundation for further exploitation bio-diesel is as follows: Firstly, the analysis method on fatty acid methyl esters of the bio-diesel from tea-seed oil wa

6、s set up by GC. It has some referenced value for establishment of national quality standard of bio-diesel. Secondly, the effect of reaction temperature, stirring intensity, molar ratio of methanol to oil , amount of cata

7、lyst and reaction time to bio-diesel yield was studied by single factor experiment. Then, the effect of each fact to bio-diesel yield was further determined by orthogonal experiment in a five-factor and four-level. The o

8、ptimized conditions of the transesterification were obtained: molar ratio of methyl to oil 5:1, amount of NaOCH3 1.2% and reaction temperature 65℃, and the yield of bio-diesel is 95.5% 。 finally, to establish the analysi
