| Abstract | The studies of pulping technology help the pulp maker to have desired properties, from which one can make the paper grades with desired end-use properties. This is a research of kraft cooking, with Eucalyptus camaldulensis wood at the different liquor to wood ratio, cooking time and alkali charge. Objective of study was to investigate the effect of cooking variables on kraft pulp yield and kappa number. Current trend toward lower kappa number is interest in modified pulping. This study discusses the changes needed in cooking variables in order to make a modification on kraft cook. The results showed that changes in liquor to wood ratio, alkali charge and cooking time affected on the properties of pulp. Higher EA concentration with lower liquor to wood ratio at the higher cooking time significantly decreased yield and kappa number. The decreased kappa number provided a pulp with lower screen rejects. In this research, it was found that EA concentration affected in pulp yield, kappa number and viscosity. |
