4. Conclusions
Mimosa, willow, giant reed and silver grass were evaluated concerning
kraft pulping performance and kraft lignins characteristics.
Mimosa wood is the most affected by pulping conditions concerning
pulp yield and KN, in the range of conditions tested. Pulping
experiments at selected conditions were successfully 5-fold scaled
up. In these conditions, mimosa, willow and giant reed presented
similar pulp yields (45–47%) andKN(13–15). Silver grass presented
the highest pulp yield (51.5%) and the lowest KN (10). This biomass
stands out also by the highest yield on lignin isolation from black
liquor.
