ZUMALACARREGUI-DE CARDENAS, Lourdes Margarita et al. Potential Uses of Bagasse for Ethanol Production Versus Electricity Production. Ing. invest. y tecnol. [online]. 2015, vol.16, n.3, pp.407-418. ISSN 2594-0732.

The procedure to carry out the energy balance for ethanol production by bagasse's hydrolysis is presented. The loss of potentialities for electric power generation when bagasse is used to produce ethanol instead of electricity directly is calculated. Potential losses are 45-64% according to the efficiency of the lignocellulosic ethanol production. The relationship that exists between the volume of ethanol and the efficiency of Otto and Rankine cycles is analyzed. Those cycles are used to produce electricity from ethanol and bagasse, respectively.

Palavras-chave : ethanol; energy; bagasse; hydrolysis; Otto cycle; Rankine cycle.
