Bioethanol is currently one of the most important biofuels which is both renewable and environmentally friendly [1, 2]. It can be blended with gasoline in various proportions or used as neat alcohol in dedicated engines, taking advantage of the higher octane number and higher heat of vaporization [3]. In addition, it is also an excellent fuel for future advanced flexi-fuel hybrid vehicles The bioethanol is an oxygenated fuel containing 35% oxygen, which reduces particulate and nitrate oxides(NOx) emissions from combustion; it is biodegrad- able and contributes to sustainability [2].
