Chemical and physical properties (density, kinematic viscosity, flash point, copper strip corrosion, calorific value) of multicomponent biofuel blends, containing rapeseed oil butyl or methyl esters, biobutanol and fossil diesel fuel are discussed in this paper. Ester, water and partial glycerides contents were determinated in multicomponent biofuel blends. These properties were compared with the same properties of pure biodiesel (rapeseed oil butyl and methyl esters) and pure diesel fuel. As there are no standards for blends fuel, containing more than 7  of biocomponents, that is why, density and viscosity were evaluated according standards EN 14214 and EN 590.It is determined that the addition of butanol and rapeseed oil butyl esters should improve the cold flow properties, such as cloud point and cold filter plugging point.As rapeseed oil butyl esters were produced from high acidity rapeseed oil (4%), much attention was deviated for oxidation stability and acidity of pure rapeseed oil butylesters and it blends with butanol and diesel fuel.

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 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

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 Stability

The physicochemical properties of biodiesel fuels and their blends prepared from four residential waste vegetable frying oils (sunflower (FSME), canola (FCME), mixture of sunflower and rapeseed (FSRME) and corn (FSCME)) were evaluated and measured to determine the best blend. The results indicate that the stability of 10 biodiesel blends was above 10 h for 0-month, meeting the stability requirement regulated in EN 14214:2014 by adding FSCME, which depends on the concentration amount of FSCME. Besides, the results showed that all fuel samples did not meet the requirements of diesel fuel standards. Therefore, automobile gasoline is used as an additive to unmixed biodiesel in various concentrations to reduce the kinematic viscosity, density and cold flow properties. The results indicate that BG85 and BG80 have met the mixed pure biodiesel with gasoline fulfilled diesel fuel quality standard. Therefore, the samples with stability above 10 h were mixed with gasoline in 15% and 20% to reduce the cold flow properties and meet the specifications of the diesel fuel standards. Moreover, the effect of long-term storage on the properties of all samples was investigated under different storage conditions. The results indicate that higher storage temperatures and longer storage periods negatively influenced the properties of the fuel samples.

Global warming has forced humanity to care for greenhouse gas emission reductions, at the same time the production and use of biofuels. One of the positive environmental properties of biofuels is fast biological degradation. Biological degradability of pure rapeseed oil fatty acid butyl esters (RBE) within 28 days is 70% and such product meets the requirements for biofuel. During the same period, only 26% of mineral diesel fuel (D) is decomposed. Multi-component fuel containing up to 30% biofuel is less biodegradable and specified as a partially biodegradable material. The peroxide and acid number of pure biodiesel is growing rapidly when aging compared to that of mineral diesel and multicomponent fuel mixtures. The acid number of pure rapeseed oil fatty acid methyl esters (RME) was higher than the standard requirements after 3 weeks of storage. The acid number of mixtures containing 15% RME (RME15B15D70) and RBE (RBE15B15D70 and RBE25B25D50) was less than 0.5 mg KOH/g–1 after 8 weeks of storage. Multi-component fuel is more resistant to oxidation than pure biodiesel fuel.

Biodiesel Quality

In manipulation and utilization of biodiesel and its mixtures, especially in the winter period, one of the most serious problems is relatively poor low-temperature flow properties. Classic methods of transesterification solve this problem, so biodiesel quality can be improved only by additives (cold flow improvers). This research examines the effect of commercial additives on the improvement of low-temperature characteristics of biodiesel. Namely, cold filter plugging point (CFPP), pour point (PP) and cloud point (CP) were tested in accordance with EN 116 and ISO 3015 standards. The influence of additives on different types of biodiesel, its different age and influence on the mixture of 5 % biodiesel and fossil diesel were examined. A better effect of additivation to "fresh" biodiesel (made using rapeseed oil), compared to "aged" biodiesel was noted. Improvement of additivation was achieved by mixing additives with an organic solvent (toluene). It was demonstrated that different types of additives are suitable for different types of biodiesel as well as mixtures of biodiesel and fossil diesel. Additives in which solvent is compatible with the type of biodiesel were found to exhibit better performance.
