Research on the Correlation between Biodiesel's Composition and Physical & Chemical Properties

Biodiesel's composition has a significant effect on biodiesel’s main physical and chemical properties. Through the test and analysis of the composition and the physical & chemical properties of 5 types of biodiesel, this paper uses linear regression model and least square method to conduct a research on the correlation between biodiesel's physical and chemical properties such as density, cold filter plugging point (CFPP), cetane number and kinematic viscosity, biodiesel's FAME content and the number of double bonds in its UFAME, and establishes correlation functions for relevant indexes, providing a theoretical basis for rapid test of biodiesel’s physico-chemical performance index.
