The blends of varying proportions of biodiesel (FAME) containing formate esters of glycerol and 93.0 wt.% fatty acid methyl esters, obtained in an interesterification reaction with methyl formate without further purification, and winter diesel fuel, were prepared, analyzed and compared with winter diesel fuel. The obtained results showed that blends comprising up to 20 vol.% of FAME fulfill the requirements of the standard LVS EN 590 concerning such characteristics as cold flow properties, viscosity, density, and carbon residue. The increase of FAME content worsens the cold flow properties; however, the mixed fuel with 20 vol.% or lower FAME content, according to the cloud point and cold filter plugging point values, remains in the same severe climate "Class 0" group as winter fuel. The carbon residue of mixed fuels raises with increasing FAME content, but stay low and do not exceed the limits of standard for mixtures with FAME percentage up to 20 vol.%. The comparison of mixed fuels containing 20 vol.% of FAME and the same amount of neat biodiesel (99.6 wt.% of fatty acid methyl esters) shows that the difference is negligible. The obtained results have indicated a good potential of FAME obtained in the interesterification reaction with methyl formate without further purification as a diesel fuel additive for up to 20 vol.%.

The main aim of the present study was to improve the oxidation stability and cold flow properties of biodiesel produced from waste frying/cooking oil and palm oil. In this work, waste frying/cooking methyl ester (WFME) and palm methyl ester (PME) were prepared using an alkali-catalyzed transesterification process, and the physicochemical properties of the pure biodiesel as well as of binary blends among them were investigated. The results indicated that palm biodiesel and WFME18, produced from a mixture of frying, cooking, sunflower, and corn oils, can be used as antioxidant additives, enhancing biodiesel stability. Additionally, it was found that WFME1 and WFME12 derived from waste residential canola oil can be used as cold flow improvers for enhancing the cold flow properties of palm biodiesel. Moreover, ultra-low sulfur diesel fuel winter (ULSDFW), ultra-low sulfur diesel fuel summer (ULSDFS), kerosene (KF), and benzene (BF) were utilized to enhance the cold flow properties of the samples and meet the requirements of diesel fuel standards. The investigation of the experimental results indicated that blending WFME-PM with a low proportion of petroleum-based fuel (KF and BF) could significantly improve the cold flow properties (CP and PP) as well as oxidation stability of WFME.

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.
