Soda cooking of rapeseed straw

Popis výsledku v původním jazyce

In this paper, the suitability of rapeseed straw for cellulosic fibre production under convectional soda pulping process was examined. Rapeseed straw (Brassica napus L. convar. napus, in our case linie genotype Labrador) was used for the pulping. On thebasis of trial pulping experiments, the cooking conditions, when rejects amount was acceptable, were selected. Hence, the batch cooks giving pulps to produce handsheets were performed at a liquor-to-straw ratio of 5:1, an alkali charge of 19 %, an anthraquinone charge of 0.1 %, and a cooking temperature of 160 °C. The pulping results were obtained for stalks of rapeseed straw and for rapeseed straw comprising stalks and valves of siliques. As would be expected, both the total yield and kappa number of pulp drop with increasing H-factor which is directly proportional to cooking time. The addition of anthraquinone to cooking liquor led to a significant decreasing in total yield and kappa number characterizing a degree of delignification o
