[en] Using the modern contactless interferometric method for determining the droplet diameter (IPI), a gas-drop flow was experimentally investigated when diesel fuel is atomized with a high-speed gas jet. The size distribution of fuel drops was obtained in different operating parameters. The dependences of drop sizes on regime parameters are revealed and analyzed. (paper)

[en] With more than 95% of India's surface transport dependent on imported fossil fuel, India has made a concerted effort to promote biofuel. The newly announced biofuel policy of India stipulates a blending target of 20% for both bioethanol and biodiesel. In the case of biodiesel, complement to fossil fuel diesel, India's predominant transport fuel, this target is to be achieved by cultivating non-edible oil seed plants in wastelands and fallow land. In spite of best effort, very little progress has been made on the ground. As the result, the deadline for blending target of 20% for biodiesel has been postponed from 2011–2012 to 2006–2017. This paper makes an attempt to understand the factors behind the tardy progress in India's biodiesel scene and suggests policy remedies. - Highlights: ► Even after a decade of efforts in promoting biofuel, India's achievement does not augur well. ► Objective is to understand the factors behind tardy progress. ► Suggests policy remedies.

[en] In the present work, chemometric methods were used for investigations of crude oils and petroleum products by statistical evaluation of spectroscopic data. The spectroscopic information was obtained by ¹H-Nuclear Magnetic Resonance and infrared experiments. Research octane numbers (RON) and motor octane numbers (MON), representing important characteristics for knocking behavior,were calculated by multilinear regression. In the period of two years it was tested whether the precision of such models was negatively influenced by varying chemical composition of the commercial gasoline. A Partial Least Squares model (PLS) was created to calculate MON. The model based on infrared spectroscopic data in the spectral region of 1400 to 650 cm¹. The standard deviation between PLS-method and the standard method ASTM D 2700 was 0,6. Another PLS-model in combination with spectroscopic data was used for calculating cetane numbers of diesel fuels. Using the spectral region of 1650 to 650 cm¹ the content of the cetane improver 2-ethyl-hexyl-nitrate could be detected. A standard deviation of 1,8 to ASTM D 613 has been achieved. An additional aim of the work was to identify crude oils by the means of principal component analysis of spectroscopic data in the near infrared region. The investigations included the determination of negative effects on data acquisition like varying temperature, water-, salt-, and sediment content. Furthermore, the density and the boiling yields in distillation of crude oils were calculated with PLS-models. (author)

[en] A comprehensive cost analysis of wind pumping system both imported and locally made versus diesel pumping systems was made.Result of the practical experience made by Energy Research Institute during the last several years and some private efforts are used in this evaluation. Economic evaluation was emphasized on the socio - economic aspects. Many problems of assumptions and adjustments of factors were also discussed and assessed. ( Author )

[en] An inquiry was initiated by the President of the Quebec Energy Board (Regie de l'energie) on October 7, 1999 to review the reasons for the wide fluctuations in the retail sale prices of gasoline and diesel fuel in the regions of Abitibi-Temiscamingue, Saguenay/Lac-Saint-Jean and the Upper Mauricie, although the Board has no jurisdiction over the prices charged for petroleum products or anti-competitive practices. Consequently, the inquiry confined itself to an analysis of the information pertaining to the structure and forces driving the petroleum products market, and an examination of price mechanisms and consumer reactions in these regions. The inquiry reviewed the relevant legislation and regulation, the social, economic and energy situations in the affected regions, and the structure and functioning of the market for gasoline and diesel fuel. The inquiry came to the conclusion that the price fluctuations during the period under review reflected the wholesale prices recorded at Montreal and Quebec, which are determined by national and international market forces over which Quebec has no significant control. Furthermore, the inquiry concluded that although market forces are present and functioning in the regions, there are relatively few outlets affiliated with major oil companies, and a large number of independent retail outlets with relatively small volumes of annual sales. They essentially set their own prices at a level that reflect their cost of operation. Appendices contain the Inquiry's mandate, a list of those who testified before the Inquiry, a map showing the geographic profile of the regions surveyed and a list of figures and tables. 18 tabs., 31 figs

[en] We investigated a remediation process for diesel-contaminated soil, in which water was used to remove the diesel from the soil and peat was used to absorb the diesel layer formed on the surface of the water. The percolation of water through the soil was uniform. The time required for water to percolate the soil and for the layers (soil, water, and diesel) to separate depended on the soil depth. Both the depth of soil and mixing affected the thickness of the diesel layer and thus diesel recovery from the contaminated soil. Higher diesel recovery was achieved with smaller soil depth and mixing. The initial moisture content and the lower heating value of the peat were 7.1% and 17.65 MJ/kg, respectively. The final moisture content and lower heating value of the diesel-contaminated peat obtained from the experiment with mixing were 8.65 - 10.80% and 32.57 - 35.81 MJ/kg, respectively. The energy content of the diesel-contaminated peat is much higher than that of coal, and the moisture content is within the range recommended for biomass gasification. (author)

[en] The seed oils of six Jatropha curcas biotypes were evaluated for their oil quality parameters and showed: oil content (38-41 %), acid value (0.14-6.94 mg/g), free fatty acid (0.07-3.47 %), iodine value (115.48-163.37 mg/g) and viscosity (0.6320-0.7431). Significant differences among biotypes were observed in oil yield and biochemical parameters. The variability among the biotypes indicate a good scope of genetic gain through selection. (author)
