O-25 竹クラフトパルプ急速熱分解における無機塩の触媒作用(燃焼・熱分解,口頭セッション)

抄録

Effects of pyrolysis temperature and addition of inorganic salts on fast pyrolysis of kraft pulp prepared from mosobamboo were evaluated. Increasing pyrolysis temperature for the kraft pulp led to increasing pyrolysate yield, which was similar to those of holocellulose and a-cellulose prepared from moso-bamboo. Compared with the holocellulose pyrolysis, the kraft pulp pyrolysis produced acetic acid in lower yield. Fast pyrolysis of kraft pulp impregnated with calcium salts produced levoglucosan in higher yield at pyrolysis temperature below 500 ℃ than that of untreated kraft pulp. Therefore, it was indicated that pyrolysis temperature and calcium salts could influence levoglucosan production from fast pyrolysis of kraft pulp.
