| Abstract:Pretreatment has become the development trend of modern pulping. Pretreatment technology of bamboo (Neosinocalamus) was studied in order to over come the liquor impregnation difficulty in pulping due to its high density. Aiming to remove as much lignin as possible and protect holocellulose from degradation, pretreatment with various temperatures, retention time and concentration of NaOH and Na2S was carried out, the remove rate of different components of the bamboo was obtained, it is the useful reference for establishing the technology of the subsequent pulping. |
