The Limits of Delignification in Kraft Cooking
The perspective of the article is to explore kraft cooking at the limits of delignification, i.e. what degree of delignification is needed to obtain fibre liberation and what is the maximum degree of delignification possible in the kraft pulping stage. The reasons for the quite narrow boundaries for sufficient and maximum delignification are explained, and the differences between the behaviour ...
متن کاملKraft: An Agent Architecture for Knowledge Fusion
Knowledge fusion refers to the process of locating and extracting knowledge from multiple, heterogeneous on-line sources, and transforming it so that the union of the knowledge can be applied in problem-solving. The KRAFT project has defined a generic agent-based architecture to support fusion of knowledge in the form of constraints expressed against an object data model. KRAFT employs three ki...
متن کاملDesorption of Metal Ions from Kraft Pulps. Part 2. Chelation of Kraft Pulps with Different Complexing Agents and with Edta in a Reducing Environment
Desorption of metal ions from oxygen-bleached hardwood and softwood kraft pulps by different chelation treatments were studied. The main focus was on desorption of manganese, iron, and magnesium ions, but also on desorption of some other common metal ions. The metal ion concentrations were determined by the DCP-AES and ICP-MS techniques. Acid treatments with nitric and oxalic acids removed mang...
متن کاملIntegration of Kraft Pulping on a Forest Biorefinery by the Addition of a Steam Explosion Pretreatment
Steam explosion has been proposed for a wide range of lignocellulosic applications, including fractionation of biomass, pre-treatment of biomass for ethanol production, or as an alternative to conventional mechanical pulping. Nevertheless, a steam explosion process could also be used as pretreatment before chemical pulping, expecting a reduction in cooking time due to the open structure of the ...
متن کاملDapsone as a second glucocorticoid-sparing agent in addition to azathioprine in treatment of pemphigus vulgaris
Background and aim: Pemphigus vulgaris is an autoimmune vesiculobullous disorder. Prior to the advent of glucocorticoid therapy, it was often fatal. Now its mortality and morbidity is due to highdose glucocorticoid complications rather than the disease itself. This study was aimed to determine the effect of dapsone as a second adjuvant in the treatment of pemphigus vulgaris.Materials and method...
