“…The presented data did not confirm the results obtained by other researchers [4,8,13], who noted the positive impact of biocomponents on CO and HC emissions compared to diesel. In the presented studies, NOx concentration increased at higher engine loads, regardless of the type of fuel and biocomponents, which is consistent with the conclusions of the authors of the study [14].…”

“…The influence of biocomponent content is not so clear, e.g., in the study [13] is stated that HVO addition decreases unregulated emissions. In contrast, the results showed in [8] prove that the FAME application, irrespective of the raw material, has a negative influence on carbonyl compound emissions.…”

“…These results confirm the conclusion in the review [12] that the emissions were significantly involved with the engine load. As in [13,17], it was found that HVO addition preferably reduces NOx concentration in exhaust gases.…”

The authors have examined the influence of biocomponents of different origin on exhaust gases emitted from a light duty vehicle with a compression ignition engine. The car was fuelled with diesel fuel containing 20% V/V fatty acid methyl esters and diesel fuel with 13% V/V hydrotreated vegetable oils and 7% V/V fatty acid methyl esters. Commercial diesel fuel containing 7% V/V esters was a reference. The tests were performed on the chassis dynamometer in static engine operating conditions. It was stated that the addition of mentioned biocomponents into diesel fuel slightly changed the concentration of regulated components in exhaust gases with/without after-treatment devices. The presence of bio-components has reduced nitrogen oxide concentration in the treated exhaust gases as compared to the commercial diesel. We observed no trends of changes in unburned hydrocarbon concentrations depending on the type of tested fuels and presence of the diesel particle filter. Unburned hydrocarbons consisted mainly of fractions containing up to five carbon atoms per molecule. Whatever the type of fuel examined, carbonyl compounds such as formaldehyde and acetaldehyde were found only in the untreated exhaust gases.

“…In contrast, transesterification-derived regular biodiesel, where fatty acids are converted to fatty acid methyl esters (FAMEs), is a conversion technology that can be economically applied at remote biomass production facilities for servicing production site and community energy and transport fuel demands today. The disadvantages of regular biodiesel production are: energy-expensive drying of biomass is required [4], limited storage time due to oxidative instability amongst others, and the reciprocal advantage and disadvantage of the long chain polyunsaturated fatty acid (PUFA) content on the cold temperature operability [cold filter plugging point (CFPP)] and the iodine value (IV), respectively [5]. Limitations can, however, be minimised by selecting a suitable algal species and manipulating the initial fatty acid profile by varying the growth conditions and extraction process.…”

Physical and chemical properties of biodiesel are influenced by structural features of the fatty acids, such as chain length, degree of unsaturation and branching of the carbon chain. This study investigated if microalgal fatty acid profiles are suitable for biodiesel characterization and species selection through Preference Ranking Organisation Method for Enrichment Evaluation (PROMETHEE) and Graphical Analysis for Interactive Assistance (GAIA) analysis. Fatty acid methyl ester (FAME) profiles were used to calculate the likely key chemical and physical properties of the biodiesel [cetane number (CN), iodine value (IV), cold filter plugging point, density, kinematic viscosity, higher heating value] of nine microalgal species (this study) and twelve species from the literature, selected for their suitability for cultivation in subtropical climates. An equal-parameter weighted (PROMETHEE-GAIA) ranked Nannochloropsis oculata, Extubocellulus sp. and Biddulphia sp. highest; the only species meeting the EN14214 and ASTM D6751-02 biodiesel standards, except for the double bond limit in the EN14214. Chlorella vulgaris OPEN ACCESSEnergies 2013, 6 5677 outranked N. oculata when the twelve microalgae were included. Culture growth phase (stationary) and, to a lesser extent, nutrient provision affected CN and IV values of N. oculata due to lower eicosapentaenoic acid (EPA) contents. Application of a polyunsaturated fatty acid (PUFA) weighting to saturation led to a lower ranking of species exceeding the double bond EN14214 thresholds. In summary, CN, IV, C18:3 and double bond limits were the strongest drivers in equal biodiesel parameter-weighted PROMETHEE analysis.

The quest of moving from conventional diesel fuels to alternate fuels is never-ending.Renewable diesel stands out as it has a similar molecular structure to that of diesel.Renewable diesel from hydroprocessing of Jatropha oil in presence of ruthenium catalyst is not much researched and the same has been worked upon in this paper. The objective of this paper is to analyze physiochemical properties of renewable diesel (R100), biodiesel (B100), and blends of diesel (D100) and renewable diesel and to check the operational feasibility. Renewable diesel was mixed in 10%, 20%, 30%, 40%, and 50%, by volume in diesel. It was observed that renewable diesel had better cold flow properties than diesel. Calorific value (CV) of renewable diesel and biodiesel was 1.84% and 3.92% less than diesel respectively. Present study shows up to 30% renewable diesel in diesel is a substitute fuel, as their viscosities (2.55, 2.60, 2.64cSt), densities (834.4 kg/m 3 , 831.87 kg/m 3 , 830.6 kg/m 3 ) and CVs (42.42 MJ/kg, 42.30 MJ/kg, 42.09 MJ/kg) are close to diesel (2.42cSt, 837 kg/m 3 and 42.57 MJ/ kg). This is also confirmed by a storage stability test conducted for 24 weeks. Cetane number of blends of R100 greater than 30% are found to be high; this can interfere with engine power output hence requiring amendments in current engines, which is not possible, therefore it is feasible to use blends only up to 30% of R100. GC-MS and Fourier transform infrared radiation showed a higher number of hydrocarbon atoms with diminutive oxygen percentage in R100, vis-a-vis, higher levels of unsaturation with more oxygen in B100.
