Acid Methyl

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.%.

Good Potential

The blends of varying proportions of biodiesel fuel containing fatty acid methyl esters and triacetin (FAME*), synthesised accordingly to Latvian patent LV 15 373 and summer diesel were prepared, analysed and compared with diesel fuel. The selected fuel properties (viscosity, density, carbon residue and cold flow properties) tested accordingly to standard LVS-EN 14214 have indicated a good potential of FAME*, obtained by synthesis of fatty acid methyl esters (FAME) by simultaneous conversion of glycerol to triacetin as a renewable diesel engine fuel. The results showed that blends containing 5 to 25% of FAME* in summer diesel yielded the properties closely matching that of diesel.Introduction
