Algae are known to be a potential feedstock in the production of biodiesel fuel. Although much of the focus has been on microalgal species, macroalgae are also suitable as a source of lipids. In this study, a locally abundant (central Illinois) filamentous algae has been harvested from a water treatment plant; dried to about 10% of its initial weight; pulverized in a hammermill; and treated wit...

Due to the rapid development of the global economy, fossil oil is widely used, leading to its depletion and gradual deterioration of the global environment, including global warming, the greenhouse effect, fog, and haze. Therefore, many researchers have been interested in studying alternative fuels in an attempt to develop an eco-friendly fuel to replace traditional fuel and solve the above env...

Blends of biodiesels produced from soapnut oil and high-oleic free fatty acids (FFAs), which are potential non-edible oil feedstocks, were investigated with respect to their fuel properties. The soapnut oil methyl esters (SNME) had satisfactory fuel properties with the exception of its high cold filter plugging point. In contrast, the biodiesel from the FFAs had favorable fuel properties such a...

The microemulsion is the emulsion with dimension of molecules approx. micrometre and smaller. Such microemulsion of water and diesel oil creates new quality and lets on obtainment ecological and economic of effects, as well as eliminates the disadvantageous influence common emulsions, or unprofitable effects of the injection of water to inlet system of the engine, direct to combustion chambers,...

Transesterification of vegetable oils in supercritical methanol are carried out without using any catalyst. Methyl esters of vegetable oils or biodiesels have several outstanding advantages among other new-renewable and clean engine fuel alternatives and can be used in any diesel engine without modification. The most important variables affecting the methyl ester yield during the transesterific...

In November 2002, the tanker Prestige broke in two and sank at the bottom of the ocean spilling about 70,000 t of fuel oil, which reached the coast of Galicia. It was considered the largest spill in maritime history, greatly affecting marine and related avian species. The spilled fuel oil contained high concentrations of polycyclic aromatic hydrocarbons (PAHs). Many species were affected and we...

The paper discusses the influence of two fatty acid methyl esters (bioesters) derived from soybean oil (SME) and from rapeseed oil (RME) on the lubricity of the petroleum diesel fuels: Ekodiesel (S:26 mg/kg, HFRR: 555 m) and Citydiesel (S: 8 mg/kg, HFRR: 617 m). High-frequency reciprocating rig (HFRR) equipment was used to examine diesel fuels, neat bioesters and blends containing from 0,1 % up...

Energy is an inescapable part of today’s society and economy. Accomplishment of every work depends on the sufficient and incessant supply of energy. But the conventional fossil energy sources like oil are ultimately limited. Moreover, the increasing demand and flinching supply of oil has made the sustainable energy supply more vulnerable. So this vulnerability of conventional source of energy c...

The objective of this research was to determine the relationship between engine performance and emissions of cottonseed oil biodiesel used in a 14.2 kW diesel engine. When using cottonseed oil biodiesel blends, CO, total hydrocarbon (THC), NOx, and SO2 emissions decreased as compared to petroleum diesel. Carbon dioxide emissions had no definitive trend in relation to cottonseed oil biodiesel bl...
