Eucalyptus globulus represents one of the most suited fibre sources for the production of a wide range of high quality papers and high-purity dissolving pulps. The optimization of kraft pulping covering both continuous and batch processes demands kinetic models suitable for advanced control and offline optimization of the cooking operation. Quite recently, an improved kinetic model structure fo...

The potential of extracellular alkali stable and thermo tolerant xylanase produced by Bacilluspumilus SV-85S through solid state fermentation was investigated in pulp bleaching in association with conventional bleaching using chlorine and chlorine dioxide. The biobleaching of kraft pulp with xylanase was the most effective at an enzyme dose of 10 IU/g oven dried pulp, pH 9.0 and 120 min incubat...

Wood polymer composites (WPC) are sensitive to moisture because of the hydrophilic nature wood fibers. The main objective this study was improve dimensional stability WPCs by coating. Polypropylene and polylactic acid were reinforced three pulp fibers (kraft, thermomechanical (TMP), chemothermomechanical (CTMP)) at fiber contents (50, 60, 70% w/w). resulting coated using two commercial coatings...
