Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...

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...

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...

How the oil spill compositions change in the weathering process is an important topic for marine environment protection. In this study, long-term weathering simulation tests were conducted for 2 kinds of crude oils from the platforms of different blocks in Bohai Sea and 2 kinds of heavy marine fuel oils. Both floating oils and oils sunken in the seawater were analyzed. Gas chromatography (GC) r...

The Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model incorporated fuel economy and electricity use of alternative fuel/vehicle systems simulated by the Powertrain System Analysis Toolkit (PSAT) to conduct a well-to-wheels (WTW) analysis of energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). Based on PSAT simulations of ...

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...

Fossil fuels have provided a convenient and plentiful energy source, and have been used profitably in all sectors of the global economy. However, continued reliance on fossil resources must take note of, and may even be placed in jeopardy by several factors. First, worldwide oil demand continues to increase, and replacing the produced oil is technically and politically demanding and very capita...
