ABSTRACT
The use of ethanol as an engine fuel became popular at the end of the 18th and beginning of the 19th century. In 1826 a prototype internal combustion engine was tested using a blend of alcohol and turpentine. In 2017, both countries contributed nearly 85% of world bioethanol production. From 1980 to 2002, the world bioethanol production presented a stability characterized by equilibrium between supply and demand, while from 2002 to 2012, there was constant growth, with the production slightly surpassing the demand. The bioethanol production where the broth is submitted to a fermentation process, producing a water-ethanol solution which is sent to the distillation towers in order to obtain the hydrated bioethanol. Since the sugarcane cycle, during colonial times, the sugar and alcohol sector has had an important role in the Brazilian social-economics system, when the Brazilian production of sugarcane has been implemented based in the plantation regime, using intensive slave manpower.
