摘要
Vineyard pruning residues were subjected to alkaline peroxide treatment for delignification. Experimental conditions maximizing lignin removal were determined by using Box-Behnken statistical experiment design. NaOH/Biomass, H2O2/Biomass and retention time were chosen as independent variables and percent lignin removal was the objective function. Experiments were done at constant Solid/Liquid ratio of 0.1 (w/w) and 135 degrees C. All parameters were found to have significant effect on lignin removal. Complete delignification was obtained in 120 min at a NaOH/Biomass ratio of 1.10 and a H2O2/Biomass ratio of 0.65. The solid residue consisted of 95% total carbohydrate indicating significant carbohydrate enrichment after complete delignification. (C) 2015 Elsevier B.V. All rights reserved.
