Abstract
Chemical properties, density and alkalinity of the black liquor obtained from kraft pulping of a selected fast growing poplar line and of reference species. Attempts were made to determine the contents of selected chemical components and the major physical properties of the black liquor obtained in the kraft pulping of selected species of trees. For the pulping process the selected 2.5-year-old fast growing poplar varieties were taken and as reference samples use was made of birch, beech, pine and poplar trees. Major chemical properties of black liquor were determined such as solids and minerals contents, and its essential physical properties such as density and alkalinity were examined. The results obtained were found to depend largely on the concentration of the pulping alkalis employed in the wood pulping process. Keywords:
