eng	Displacement Washing of Kraft Pulp Cooked from Beech Wood	The aim oť this work was to investigate the displacement washing of kraft pulp manufactured from beech. The experiments were carried out in a laboratory washing cell. In order to characterise the pulp fibres, the degree of freeness. kappa number, fibre length. as well as the specitlc volume and specific surťace of swollen fibres were determined as well. The displacement washing process was deseribed by displacement washing curves recorded for alkali lignin as a tracer. Mathematical treatment of the washing curves. obtained as a response to the step input signál, gave the Péclet number characterising the displacement of alkali lignin from the pulp pad. For detailed deseription of the displacement washing process. further parameters. such as the traditional wash yield, axial dispersion coeffícient. as well as the mean residence lime and the space time. were also evaluated.	beech;displacement washing efficiency;pulp
