Question:
A second-generation bioethanol production facility processes biomass that contains cellulose (assume glucose for the calculations), hemicellulose (xylose), and lignin. The plant is supposed to operate self-sufficiently, but the energy consumption is 10% lower than the production. The uncertainty is in the conversion of xylose to glucose.
The conversion from glucose to ethanol is 90%, and that from xylose should be 80%. Ninety-six percent (96%) of the ethanol produced is recovered. If the fraction of cellulose and hemicellulose in the feedstock is the same, the consumption of energy is 7000 kJ/kg of ethanol produced; it is possible to obtain up to 19,500 kJ/kg of lignin.
Compute the actual conversion of xylose and the ethanol production of the facility per 100 kg of initial biomass.
