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 compositions and kinematic viscosity of Pistacia Chinensis-based biodiesel (PCME) are investigated. Viscosity temperature equations are proposed for predicting kinematic viscosity of PCME and its blends with 0 petrodiesel (0PD) /-10 petrodiesel (-10PD) at different temperature. In this work, we show that PCME is mainly composed of fatty acid methyl esters of 14-24 even-numbered C atoms: C14:0-C24:0, C16:1-C22:1, C18:2-C20:2 and C18:3. PCME has higher kinematic viscosity and unfavorable viscosity temperature property, its kinematic viscosity (40 °C) is 5.99 mm2/s. An approach to reduce viscosity and enhance viscosity temperature property is put forward: blending with 0 PD/-10PD.

Possible alternative raw materials for producing biodiesel fuel are as follows: Camelina sativa oil, fibre linseed oil and waste animal fat. The aim of this work was to analyse the emissions of the engine running on multi-component fuels containing fossil diesel fuel (D), linseed or Camelina sativa oil fatty acid methyl esters (LSME and CME respectively) and beef tallow (TME) fatty acid methyl esters. The concentration of fatty acid methyl esters (FAME) in the mixtures with fossil diesel fuel varied from 10% to 30%. The mass proportion of LSME (or CME) and TME in the mixtures was 1:4. The lowest NOxconcentration in exhaust gases was observed when the mixtures contained 10% of biofuel. For the mixtures containing CME and LSME, NOx concentrations reached 290 and 295 ppm respectively when the engine rotation speed was 1200 min−1 and 370 and 375 ppm respectively when rotation speed was 2000 min−1. CO concentration was the lowest when fuel contained 30% of the FAME mixture. HC concentration was slightly higher when the mixtures containing LSME were used relative to the mixtures containing CME. The amount of HC did not fluctuate considerably (195÷254 ppm) at rotation speeds between 1200 and 2000 min−1. Lower HC concentration was found in exhaust gas when the fuels containing 10% and 20% of biofuel were used. The lowest concentration of polycyclic aromatic hydrocarbons (PAHs) was found when the mixtures contained 30% of biofuel made of LSME or CME corresponding to 30 µg/m3 and 38 µg/m3 at a rotation speed of 1200 min−1 and 640 µg/m3 and 670 µg/m3 at a rotation speed of 2000 min−1 respectively. The greatest amount of smokiness at a high rotation speed of 2000 min−1 was observed when the mixture contained 30% of multi-component biodiesel fuel. It was found that the fuel containing a mixture of 30% of LSME biofuel and 20% of CME biofuel had a small advantage.

Studies were carried out to produce potential biodiesel from non-edible oil of Jatropha curcus. Due to its high free fatty acid (12% FFA), the crude Jatropha oil was processed in two steps: the acid-catalyzed esterification and followed by the base-catalyzed transesterification. The first step reduced the FFA level to less than 1% in 1h at 50°C for the 0.40 w/w methanol-to-oil ratio with 1% w/w of H2SO4. After the reaction, the mixture was stagnated for an hour and the methanol-water upper layer was discarded. The second step converted the product of the first step into biodiesel and glycerol through transesterification using 0.20 w/w methanol-to-oil and 0.5% w/w NaOH to oil as alkaline catalyst at 65°C. The maximum yield of biodiesel (organic phase of upper layer) and fatty acid methyl esters (FAME) yield were achieved at about 95% and 84% within 1 hour respectively. The glycerol concentration in the byproduct (glycerol layer) obtained after dual step transesterification was found 32%.
