A Review on Environmental Friendly Gasoline Substituent: Bio-ethanol

The recent energy concern and environment saving issue motivate us for thinking about alternative environment friendly energy source such as bio fuel (mainly Bio ethanol). Bio ethanol is a choice for high octane number and low cetane number. Cellulosic feed stocks can be employed for bio ethanol production very effectively. One citable problem with Bio ethanol generation is the unavailability of raw materials. Several modern measures are taken for Bio ethanol generation in now a day to negotiable the drawbacks. This paper review the history, worldwide status, producing processes and future aspect of Bio- ethanol.
