Bioethanol has been identified as the mostly used biofuel worldwide since it significantly contributes to the reduction of crude oil consumption and environmental pollution. It can be produced from various types of feedstocks such as sucrose, starch, lignocellulosic and algal biomass through fermentation process by microorganisms. Compared to other types of microoganisms, yeasts especially Sacc...

In the present study, the effects of bioethanol-diesel fuelBeraid ED10 additive blends on engine performance and emissions were investigated on a four-stroke, three-cylinder, water-cooled, turbocharged diesel engine with a pump injection fuel system. Low-sulphur Eurodiesel fuel, BE5 (5% bioethanol – 93% euro diesel – 2% Beraid ED10), BE10 and BE15 fuels were used in the experiments. The changes...

Bioethanol production output has increased steadily over the last two decades and is now beginning to become competitive with traditional liquid transportation fuels due to advances in engineering, the identification of new production host organisms, and the development of novel biodesign strategies. A significant portion of these efforts has been dedicated to mitigating the toxicological chall...

With the limited fossil fuel resources and aggravating energy crisis, coupled with the concern about the climate change caused by greenhouse gases, many people hope that renewable fuels will be developed as an alternative to fossil fuels, with special attention being paid to bioethanol.1,2 Compared to fossil fuels, biofuels emit less ozone, benzene, carbon dioxide and other harmful pollutants. ...

<strong>ABSTRACT. </strong>Bioethanol is an alternative energy sourced from environmentally friendly raw materials wastes that contain a lot of lignocellulosic such as HVS paper. Paper contains about 85% cellulose, 8% hemicellulose, 5% lignin and the rest in form ash compounds. Bioethanol ethanol produced fermentation glucose (sugar) followed by distillation process. This study aims...

Bioethanol production is an established biotechnological process. Margins are low which prevent a larger scale of bioethanol. As large part the cost due to feedstock, use value unsterile feedstocks fermented by microbial communities will enable more cost-competitive bioethanol production. To select for high yield ethanol producing communities, three selective conditions proposed: acid washing c...

Lignocellulosic materials such as agricultural residues have been recognized as potential sustainable sources of mixed sugars for fermentation to bioethanol. To obtain a high overall ethanol yield and achieve an economically feasible production process, the removal of lignin and hemicelluloses improves the accessibility of cellulosic material to hydrolytic enzymes and avoids the degradation pro...

One of the most important parameter for spark ignition engines is volumetric efficiency, as it directly influences specific power output. Several definitions of this parameter are studied from a theoretical point of view, taking into consideration the use of alternative fuels. The influence of using gasoline-bioethanol blends is investigated, as well as the effect of fuelling spark ignition eng...

The conversion of biomass into biofuels can increase fuel flexibility and reduce the related strategic vulnerability of petroleum based transportation fuel systems. Bioethanol has received considerable attention over the last years as a fuel extender or even neat liquid fuel. Lignocellulosic materials are very attractive substrates for the production of bioethanol because of their low cost and ...

BACKGROUND Bamboo is potentially an interesting feedstock for advanced bioethanol production in China due to its natural abundance, rapid growth, perennial nature and low management requirements. Liquid hot water (LHW) pretreatment was selected as a promising technology to enhance sugar release from bamboo lignocellulose whilst keeping economic and environmental costs to a minimum. The present ...
