Study on Cold Flow Properties of Waste Cooking Methyl Ester

Abstract:

The chemical compositions of waste cooking methyl ester (WCME) were analyzed by GC-MS, and the cold flow properties of WCME were studied by cold filer plugging point tester and viscosity tester. Through blending with petrodiesel and adding cold flow improver (CFI), the cold flow properties of WCME were improved efficiently. The study shows that WCME was mainly composed of saturated fatty acid methyl ester (SFAME) and unsaturated fatty acid methyl ester (UFAME), and contents of SFAME and UFAME were 27.63 and 71.81 w%, respectively. The cold filer plugging point (CFPP) of WCME was 0 °C, and the viscosity of it was 4.41 mm2·s-1 at 40 °C. Blending with 0 petrodiesel (0PD) and-10 petrodiesel (-10PD) decreased the CFPP of WCME to-4 °C and-13 °C, respectively. Meanwhile with WCME blending ratio increasing the viscosities of blending oils increased at the same temperature, and the viscosities increased gradually when the temperature decreased. Treating with CFI could significantly reduce the CFPP of blending oils which were composed of WCME and petrodiesel. The viscosities of blending oils with adding CFI were slightly higher than those with out CFI.
