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.

The composition of palm methyl ester (PME) was determined and quantified by Gas chromatography-Mass spectrometer (GC-MS). Cold flow properties of PME was studied by means of cold filter plugging point tester and kinematic viscosity tester and the solution crystallization theory, at the same time to observe the crystalline mechanism with low temperature phase contrast microscope. Experimental results showed that PME was mainly composed of saturated fatty acid methyl ester (SFAME) and unsaturated fatty acid methyl ester (UFAME), PME has a poor cold flow properties because of its more SFAME content. Observation results of the microscope showed that, the crystallization of PME at a steady cooling rate was lamellar crystal for rules. With the reduction of temperature, lamellar crystal increased gradually, and aggregated together. The higher the cooling rate was, the smaller the lamellar crystal and the irregular shape was.

The chemical compositions of cottonseed oil biodiesel (CSME) are analyzed by using the gas chromatograph-mass spectrometer (GC-MS). The cold flow properties of CSME is studied by cold filer plugging point (CFPP) tester and crystallization mechanism of biodiesel, three approaches for enhancing cold flow properties of CSME are put forward: crystallization fractionation; blending with winter petrodiesel; and treating with cold flow improver (CFI) additives. A significant correlation model is proposed for predicting CFPP by CSME blending ratio. The study shows that the CSME is mainly composed of saturated fatty acid methyl esters (SFSMEs): C14:0~C24:0 and unsaturated fatty acid methyl esters (UFAMEs): C16:1~C22:1, C18:2 and C18:3. The mass fraction of SFAME and UFAME is 32.12 and 66.19%, respectively. The CFPP of CSME is 6 °C. Crystallization fractionation and blending with-10PD decrease the CFPP of CSME to-1 °C and-12 °C, respectively. Adding Flow Fit, Flow Fit K and T818 additives 1.5 v% decreases the CFPP of CME and CME/-10PD to 0 and-26 °C, respectively. This study has effectively enhanced cold flow properties of CSME and provides technical support for using CSME.

Significant Linear Correlation

This paper studies the chemical composition of biodiesel, cold flow properties, and the influence of chemical composition on cold filter plugging point (CFPP) by using GC-MS and CFPP tester according to the theories of crystallization. Using the method of multivariate linear regression to analyze the correlation between chemical composition and CFPP, the prediction model of CFPP which has a very significant linear correlation and is based on chemical composition is built. The study shows that biodiesel is mainly fatty acid methyl ester (FAME) that is composed of 14-24 even number carbon atoms (C14:0~C24:0 , C16:1~C22:1, C18:2~C20:2 and C18:3). The CFPP increases linearly with the increase of the content of SFAME and the longer the carbon chains are, the greater the increase will be; the CFPP decreases linearly with the increase of the content of UFAME. Among the 120 kinds of biodiesel we studied, the CFPP of Chinese tallow methyl ester (CTME) is the lowest (-14 °C) and the CFPP of peanut methyl ester (PNME) is the highest (13 °C).

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.

The chemical compositions of biodiesel derived from palm (PME) were analyzed by gas chromatography-mass spectrometry (GC-MS). The cold flow properties of PME were studied by multifunctional low temperature tester, differential scanning calorimetry (DSC) and solution crystallization theory. Three approaches for improving cold flow properties of PME were put forward: crystallization fractionation, blending with winter petrodiesel and treating with cold flow improver (CFI) additives. A good correlation model was proposed for prediction cold filter plugging point (CFPP) by winter petrodiesel blending ratio. The study shows that the PME was mainly composed of saturated fatty acid methyl esters (SFAME): C14:0-C24:0 and unsaturated fatty acid methyl esters (UFAME): C16:1-C22:1, C18:2 and C18:3. The mass fraction of SFAME and UFAME was 35.86% and 62.83%, respectively. The CFPP of PME was 8°C. Crystallization fractionation and blending with -10 petrodiesel (-10PD) decreased the CFPP to 0 and -12°C, respectively. Treating with CFI additives (volume fraction ≤ 1.5%) decreased the CFPP of PME and PME/-10PD to 2 and -26°C, respectively. This study has effectively improved cold flow properties of PME and provided theoretical support for using PME during cold weather.
