The natural energy resources such as fossil fuels (petroleum and
coal) are being utilized at a rapid rate and these fossil fuel resources
would last only for few more years [1]. From various alternative
energy resources, bio-ethanol is the most promising
resource because of its biological and renewable origins, normally
derived from energy crops such as maize, sugarcane, cassava,
sweet potato, mahula flower and by-products of agriculture and
forestry [2]. Biofuels offer a number of environmental, social, and
economic advantages, lower emission of harmful pollutants and
good fuel properties for vehicles
