Fuel ethanol releases can stimulate methanogenesis in impacted aquifers, which could pose an explosion risk if methane migrates into enclosed spaces where ignitable conditions exist. To assess this potential risk, a flux chamber was emplaced on a pilot-scale aquifer exposed to continuous release (21 months) of an ethanol solution (10% v:v) that was introduced 22.5 cm below the water table. Desp...

The main aim of this study is to investigate Aganonerion polymorphum leaf-ethyl acetate extract (APL-EAE) and its inhibiting effect for steel in ethanol fuel blend. The immersion test, electrochemical and surface analysis techniques were successfully carried out in this research. Scanning electron microscope images indicated that the ethanol fuel blend induced pitting corrosion of steel. Remark...

Pacific Economic Bulletin Volume 24 number 3 october 2009 © the australian national university Fiji is totally dependent on imported fossil fuel for its transport sector and options for alternative motor fuels are limited. In the past, when petroleum prices soared, there were discussions at various levels about alternatives. These discussions might have been sporadic but the seriousness of the ...

Over the last decade, microbes have been engineered for the manufacture of a variety of biofuels. Saturated linear-chain alcohols have great potential as transport biofuels. Their hydrocarbon backbones, as well as oxygenated content, confer combustive properties that make it suitable for use in internal combustion engines. Herein, we compared the microbial production and combustion characterist...

In this study, the effects of adding ethanol and diethyl ether to diesel fuel on combustion characteristics NO emissions were numerically investigated. 100% (D100) by volume 90% diesel+10% blend (D90E10), 80% diesel+20% (D80E20), ethanol+10% (D80E10DEE10) 85% diesel+ 10% ethanol+5% mixture (D85E10DEE5) was used as fuel. Analyzes carried out using a single cylinder direct injection engine at 200...

Background: One of the challenges facing the fuel ethanol industry is the management of bacterial contamination during fermentation. Lactobacillus species are the predominant contaminants that decrease the profitability of biofuel production by reducing ethanol yields and causing “stuck” fermentations, which incur additional economic losses via expensive antibiotic treatments and disinfection c...

An experimental investigation is carried out to establish the performance and emission characteristics of a compression ignition engine while using cerium oxide nanoparticles as additive in neat diesel and diesel-biodiesel-ethanol blends. In the first phase of the experiments, stability of neat diesel and diesel-biodiesel-ethanol fuel blends with the addition of cerium oxide nanoparticles are a...
