Study on the production biodiesel utilizing cormus wilsoniana fruit Oil

Cormus wilsoniana wanger is a woody oil plant with wide distribution,high-yield and high-oiliness characters.In this paper the process for Cornus wilsoniana oil to production bio-diesel was studied,and physical-chemical characteristics of producing bio-diesel were analysed.The optimums conditions of esterification with Cormus wilsoniana oil were studied by designing L9(3 4) orthogonal experiments.It shows that the fuel characteristics of the bio-diesel,processed by the transesterification of Cormus wilsoniana oil,are the same as that of diesel.But the bio-diesel is safety (flash point 105 ℃),clean (ash0.003) and reproducible.The optimum conditions calculated by orthogonal experiments are A_ 1 B_ 3 C_2D_ 3 .
