An experimental investigation has been carried out for the first law analysis of a DI (direct-ignition) diesel engine running on straight soybean oil (SVO) preheated at 50, 75, 100C with different loads at varying speeds of 1750, 2000, 2250 rpm. The results show that preheated straight soybean oil may be a practical replacement of the conventional diesel fuel with a small power and efficiency d...

In this study, we estimate rice residue, associated burning emissions, and compare results with existing emissions inventories employing a bottom-up approach. We first estimated field-level post-harvest rice residues, including separate fuel-loading factors for rice straw and rice stubble. Results suggested fuel-loading factors of 0.27 kgm (±0.033), 0.61 kgm (±0.076), and 0.88 kgm (±0.083) for ...

This paper identified the factors influencing the rice crop residue burning decision of the farmers and the potential of the burnt residue to generate electricity. For this study, data were collected from 400 farmers in the rice-wheat cropping system. Effects of different variables on the burning decision of rice residue are investigated through logit model. A number of factors had significant ...

A supercritical methanol transesterification method was applied to produce biodiesel from the high-acid oil of soybean soapstock. The fuel properties of biodiesel produced with various molar ratios of methanol to raw oil were analyzed and compared in this experimental study. Oleic acid (C18:1), linoleic acid (C18:2), and palmitic acid (C16:0) were the three main compounds in the high-acid oil-b...

plants firing fuel oil produce huge quantities of fly ash as solid waste, which needs to becharacterized prior to its proper management. it is worth mentioning that the published literature lackcomprehensive information on the characteristics of such fly ash. characteristics of fuel oil fly ash producedat selected power (pp) and water desalination (dp) plants were determined. the results showed...

Energy conservation is important for most of the developing countries, including rest of the world. The rapid depletion in world petroleum reserves and uncertainty in petroleum supply due to political and economical reasons, as well as the sharp escalations in the petroleum prices have stimulated the search for alternatives to petroleum fuels. The situation is very grave in developing countries...

leaving crop residues on the soil surface may significantly affect the behavior and activity of herbicides. in order to study the effect of wheat residue and different rates of trifluralin (%48 ec) herbicide on the yield and oil content of sunflower (helianthus annuus) a field experiment was done in agricultural research station, the university of birjand in summer 2008. experimental design was...

We argue that sequestering of carbon waste is inherently more efficient and will probably cost less than using the carbon for biomass burning. The ratio of carbon emitted per unit of primary energy released through combustion, C/E, favors sequestration for fundamental reasons of chemistry and engineering, strongly suggesting a low C/E strategy. This is a more direct way of analysis than assigni...

Several series of chronic experiments in white mice and white rats were carried out in order to determine the carcinogenicity of Estonian oil shale soot as well as the soot from oil shale fuel oil. All the investigated samples of soot showed a relatively low (from 14 to 1200 ppm) benzo(a)pyrene content. The benzene extract of oil shale soot, painted on the skin of white mice, proved to be stron...
