Effects of Kraft Pulping on the Interfacial Properties of Eucalyptus Pulp Fibres
Os efeitos da polpação kraft nas propriedades interfaciais da polpa de eucalipto brasileiro foram investigados usando titulação com polieletrólito (PT) e medidas de ângulo de contato. Mudanças na composição química da superfície foram avaliadas por espectrometria de reflexão total atenuada no infravermelho (FTIR-ATR), combinada com análise de componentes principais (PCA). O aumento do álcali at...
متن کاملOn the Recovery of Hemicellulose before Kraft Pulping
To assess the feasibility of implementing hemicellulose recovery stages in kraft mills, Eucalyptus globulus wood samples were subjected to aqueous treatments with hot, compressed water (autohydrolysis processing) to achieve partial dissolution of xylan. Autohydrolyzed solids were subjected to kraft pulping under selected conditions to yield a pulp of low kappa number, and to an optimized TCF bl...

15 صفحه اولComprehensive Kinetic Study of Delignification, Carbohydrate Degradation, Cellulose Chain Scissions, and Hexenuronic Acid Reactions during Kraft Pulping of Eucalyptus Globulus
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...
متن کاملThe relationship of pretreatment pulping parameters with respect to selectivity: optimization of green liquor pretreatment conditions for improved kraft pulping
Green liquor ( GL ) was used as a sulfide rich liquor to impregnate Southern pine wood chips in a pretreatment step for kraft pulping. A central composite experimental design was applied to investigate relationships between pretreatment conditions, chemical absorption, pulping selectivity, and primary pulp qualities. The derived equations provided a correlation between the independent cooking v...
