The analysis of the results obtained in this work have shown
that the conditions determined in each stage influence strongly
the performance of the other stages and the challenge is to find
the best combination of conditions for the integrated process.
Although a technical analysis shows that AHP pretreatment is
the best one, sulfuric acid pretreatment has the lowest reagent
consumption. Furthermore, if separated pentoses and hexoses
fermentation is considered, with pentoses used for the ethanol
production or other products, acid pretreatment is the most
adequate, as it produces the liquors with the highest monomeric
pentoses recovery.
