| Abstract: | Fuel ethanol has become one of the most important liquid fuels because of the shortage of fossil fuels.In this paper the production of starchiness-based fuel ethanol is reviewed,from the pretreatment of raw material to the dehydration of product.Different technologies are discussed and their energy consumptions are analyzed to find out the best technical route for the producers based on the statistics.There are five steps to manufacture ethanol,and liquefaction and distillation are the important ones,as they consume more energy than others.Waste treatment is discussed based on different raw materials.These results can be useful for the producers. |
