Kraft Pulping of Softwood Chips with Mild Hot Water Pre-hydrolysis to Understand the Effects of Wood Chip Thickness

open access: yesBioResources, 2022
Hemicelluloses consume alkali during kraft pulping and dissolve in the black liquor as a low energy fuel. Acidic pre-hydrolysis of softwood chips removes hemicelluloses but preserves cellulose content prior to pulping.
