The process of degradation biodiesel vegetable origin (rapeseed and sunflower) under the influence various factors is considered. Existing methods determining microbiological contamination substances are analyzed, their main advantages, disadvantages, limits use determined. Based on combination existing methods, a method qualitative quantitative determination degree (bacterial mycological) dama...

Bio-diesel the mono-alkyl esters of vegetable oils can serve as sustainable energy resources alternative to depleting fossil fuels and has gained more importance due to its clean environmental benefits, renewability and biodegradability. The proposed paper highlights the results of experimental investigations on the scope of utilizing biodiesel manufactured from Polanga and Jatropha oils as an ...

Contamination in subsurface environment is a serious environmental hazard. Main sources of the contamination are petrol, diesel fuel, gasoline at oil refineries, underground storage tanks, transmission pipelines and different industries. Permeable reactive barriers (PRBs), which promising technology to remediate groundwater in-situ, filled with materials for removal contaminants present groundw...

Identification of sources of polycyclic aromatic hydrocarbons (PAH) in sediments is an important step in reducing anthropogenic contamination. Identifications based solely on the composition of PAH can be confounded by compositional changes during weathering and biodegradation. Stable isotopic composition of individual PAH offers an additional marker, which can aid in distinguishing sources and...

This paper presents an experimental investigation on a four-stroke single cylinder diesel engine fuelled with the blends of Mahua oil methyl ester (MOME) and diesel. The performance emission, energy, and exergy analysis has been carried out in B20 (mixture of 80% diesel by volume with 20% MOME). From energy analysis, it was observed that the fuel energy input as well as energy carried away by e...

The objective of this study was to test the performance of diesel engine using diesel B3 mixed with crude palm oil in ratios of 95 : 5, 90 : 10, and 85 : 15, respectively, and to compare the results with diesel B3. According to the tests, they showed that the physical properties of the mixed fuel in the ratio of 95 : 5 were closest to those of diesel B3. The performance of the diesel engine tha...
