Modelling of pulp characteristics in kraft cooking

open access: yes, 2004
Abstract This paper discusses a Kappa-number estimator using different modelling approaches in continuous cooking. Alkaline, total dissolved solids and lignin content are measured on-line from several circulations in a continuous digester. ABB’s Cooking Liquor Analyser (CLA 2000) and an on-line Kappa-number measurement were used in this research.

Effect of Acacia melanoxylon wood density on papermaking potential [PDF]

open access: yes, 2007
In this work we study the behaviour in kraft cooking and papermaking of 6 Acacia melanoxylon wood chip samples, with basic densities of 449, 489, 493, 505, 514 and 616 kg/m3. The wood chip samples were screened and submitted to the kraft cooking process.

Two Tales of Uncertainty: Calibrating Overprecision With Self‐Regulated Entrepreneurial Learning

open access: yesStrategic Change, EarlyView.
ABSTRACT Entrepreneurial success strongly depends on decision‐making under uncertainty. Uncertainty is particularly pronounced when entrepreneurs are confronted with novel situations characterized by an absence of information. While cognitive biases, such as overprecision, can have a negative impact on decision‐making processes by distorting ...

Temperature and effective alkali effect on brown pulp kraft cooking

open access: yesNordic Pulp & Paper Research Journal, 2021
Abstract One way to obtain high quality pulp production is to improve selectivity delignification of step, maximize yield. Brown pulp yield and chemical composition were studied, with variation of temperature and effective alkali in Kraft cooking.

Investigation lignin dissolution at pulping process of wheat straw [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2010
The lignin dissolution in Kraft pulping for wheat straw was studied. Kraft pulping was carried out under the conditions: chemical charge of 18% (as NaOH, based on o.d. bagasse), sulfidity of 25% and liquor to wheat straw ratio of 10:1.

EFEITO DOS SÓLIDOS DISSOLVIDOS DA MADEIRA NA BRANQUEABILIDADE E NAS PROPRIEDADES FÍSICO-MECÂNICAS E ÓPTICAS DE POLPA KRAFT BRANQUEADA DE EUCALIPTO

open access: yesCiência Florestal, 2012
Many studies have shown that the yield of kraft pulping can be improved by xylan reabsorption to the pulp during the cooking, and kraft black liquor contains significant fraction of xylan from wood, an important source of these macromolecules.
