Reduce Cold Filter Plugging Point and Kinematic Viscosity of Cottonseed-Based Biodiesel Fuel

Article Preview

Abstract:

The chemical compositions, cold filter plugging point (CFPP) and kinematic viscosity of cottonseed methyl ester (CSME) are investigated. Through blending with-10 petrodiesel (-10PD) and treating with Flow Fit, the CFPP and kinematic viscosity of CSME are improved. The study shows that CSME is mainly composed of fatty acid methyl esters (FAME), and the contents of saturated fatty acid methyl ester (SFAME) and unsaturated fatty acid methyl ester (UFAME) were 27.69% and 71.65% respectively. The CFPP and kinematic viscosity (40 °C) of CSME are-1 °C and 4.63 mm2/s respectively. Blending with-10PD decreased the CFPP of CSME to-12 °C.With temperature decreasing, the kinematic viscosities of CSME and CSME/-10PD increase. The lower the temperature is, the more differenced the kinematic viscosities of CSME and CSME/-10PD are. Treating with less than 3% (volume fraction) of Flow Fit, the CFPP of CSME and CSME/-10PD decreased significantly.
