Alkaline Pulping with Additives of Southern Cattail Stems from Sudan
s: Soda-anthraquinone (soda-AQ) alkaline sulfiteanthraquinone (AS-AQ) and ASAM (alkaline sulfiteanthraquinonemethanol) cooking of southern cattail whole stem and bark from Sudan was carried out under different conditions and pulps with acceptable to good screened yields and very good mechanical properties were attained. The southern cattail whole stems gave satisfactory mechanical properties wi...
متن کاملAlkaline Sulfite Anthraquinone and Methanol Pulping of Bamboo (Gigantochloa scortechinii)
Alkali ratios and cooking time of the alkaline sulfite anthraquinone (AQ) and methanol (ASAM) pulping process of bamboo (Gigantochloa scortechinii) were studied. Bamboo chips were cooked at three different levels of sodium hydroxide and cooking time, namely 14, 16, or 18% for 60, 90, or 120 minutes. Pulping parameters that remained constant were the use of 0.5% ethylene diamine tetraacetic acid...
متن کاملOptimal Operating Points in Alkaline Pulping
1 Author to whom correspondence should be addressed Abstract The problem of optimizing the alkaline impregnation of wood chips is posed and solved under usual restrictions. The cost to be optimized balances opposite criteria by taking economics and product quality into account, and is conditioned by the system dynamics. Evolution is modeled from typical transport phenomena equations. Optimizati...
متن کاملMultifunctional Alkaline Pulping, Delignification and Hemicellulose Extraction
In this study, multifunctional alkaline pulping was suggested to produce different pulp grades at one mill site, ranging from high-yield paper pulp to high-purity dissolving pulp. In all process modifications, sulfur was successfully replaced by anthraquinone. Autohydrolysis and alkaline pre-extraction were applied to Eucalyptus globulus wood chips, followed by kraft and soda-AQ pulping. Alkali...
متن کاملInfluence of Operating Variables and Model to Minimize the Use of Anthraquinone in the Soda-Anthraquinone Pulping of Barley Straw
Soda-anthraquinone (soda-AQ) pulping of barley straw was used to obtain cellulosic pulps for papermaking purposes. The identified parameters, or variables to be optimized, were operating time, anthraquinone concentration, and PFI refiner revolutions, and the influence of these operating variables on pulp properties was studied. A polynomial model that reproduced the experimental results with er...
