EVALUATION OF CHEMICAL COMPOSITION AND LIGNIN STRUCTURAL FEATURES OF SIMAROUBA VERSICOLOR WOOD ON ITS PULPING PERFORMANCE

BioResources, 2012
Simarouba versicolor wood was evaluated relative to its kraft pulping ability and compared with Eucalyptus urograndis wood. Comprehensive chemical analysis of wood and milled wood lignin (MWL) was performed, aiming to correlate wood and lignin structural

Pulp Production from Cotton Stalks using Kraft Pulping

, 2015
The study aimed at optimizing pulping variables and selecting suitable delignification conditions for the production of pulp from cotton stalk. The influence of operational variables on the pulp yield and lignin dissolution of cotton stalks was studied. Cotton stalks chips were delignified in a laboratory pulpwood according to the Kraft pulping process.
