Prediction of blackwood Kraft pulps yields with wood NIR ...
Samples of 25 g oven-dried wood were milled using a knife mill (Retsch) with a 1-mm output screen, and the fraction coarser than 0.25 mm was used for kraft pulping with a multi-batch digester system under the following reaction conditions: active alkali charge 21.3 % (as NaOH); sulfidity 30 %; liquor/wood ratio 4:1; time to temperature of 160 ...
