Evaluation of Alkaline Delignification (Naoh) of Açaí Seeds (Eutherpe Oleracea) Treated with H2so4 Dilute and Effect on Enzymatic Hydrolysis

open access: yesChemical Engineering Transactions, 2015
Ethanol production from lignocellulosic residues from agriculture, such as the acaí seeds, have a fundamental step, delignification. This step becomes is more effective when performed in combination with others pre- treatments, preferably with those that
