Lignin chemistry and topochemistry during kraft delignification of Eucalyptus globulus genotypes with contrasting pulpwood characteristics
(Walter De Gruyter Gmbh, 2014-08-01)
Eucalyptus globulus Labill. is a short-fibre resource for pulp and paper production. Ten different E. globulus genotypes with varied pulpwood quality and chemical composition were evaluated under kraft pulping conditions. ...
Structural, morphological, and thermal characterization of kraft lignin and its charcoals obtained at different heating rates
(Iop Publishing Ltd, 2018)
Biomass is a renewable resource that is becoming more import due to environmental concerns and possible oil crisis. Thus, optimizing its use is a current challenge for many researchers. Lignin, which is a macromolecule ...
Effect of S/G ratio on kraft pulping and ECF bleaching of some poplars and eucalyptus
(2014-01-01)
The effect of syringyl:guaiacyl (S/G) ratio on kraft pulping and kraft pulping followed by O2 delignification was investigated with six poplars grown on the same site. The results showed an improvement in the ease of ...
