Evaluation of kraft cooking behaviour for different hardwood species [PDF]
, 2010 In this study six wood species (birch, chestnut, oak, beech, poplar and eucalyptus) were analysed separately. Lignin content, Polysaccharides content (cellulose and hemicelluloses), Yield, Hexenuronic acids were evaluated for three cooking temperatures

, 2017 In this paper, pulping of wheat straw with Kraft process was studied. Chemical and morphological properties of wheat straw fibers were also investigated. Chemical properties including cellulose (39.8%), hemicellulose (29.47%), lignin (20.98%), ash (6.27%) and extractives (4.1%) were determined.

Adição de antraquinona na polpação alcalina de Eucalyptus saligna
Ciência Florestal, 2000 The present work evaluated different alkaline pulping conditions for Eucalyptus saligna wood. The objective was to evaluate the influence of the anthraquinone (AQ) on the reduction of the total reduced sulfur (TRS) in the aerial emissions, by reducing ...

Biorefinery of agricultural residues by fractionation of their components through hydrothermal and organosolv processes [PDF]
, 2010 The combined production of the most abundant agricultural residues in Spain (viz. cereal straw, sunflower stalks, vine shoots, cotton stalks, olive, orange and peach tree prunings, and horticultural and related residues) amounts to over 50 million tons ...

DELIGNIFICATION OF SUGARCANE BAGASSE WITH ALKALI AND PERACETIC ACID AND CHARACTERIZATION OF THE PULP
BioResources, 2010 Sugarcane bagasse was delignified with alkali and peracetic acid in a two-stage process to obtain pulps with high yield and low kappa number. The experimental results indicated that alkali pretreatment prior to peracetic acid (PAA) delignification could ...

APROVEITAMENTO DA CASCA DO COCO-VERDE (Cocos nucifera L.) PARA PRODUÇÃO DE POLPA CELULÓSICA
Ciência Florestal, 2016 The coconut husk is a residue from consumption of coconut water. In coastal cities this residue has already become a big problem, because it is difficult to decompose.
