Multi-stage Bagasse pulping by using alkali/Caro's acid treatment
چکیده انگلیسی
Bagasse delignification by using separate alkali and Caro's acid treatments is considered as a promising process to prepare high-yield bagasse pulp. This could be achieved via two-stage technique (NaOH/Caro's acid) and three-stage technique (NaOH/Caro's acid/NaOH). The two techniques were practiced at low temperatures and atmospheric pressure. Three-stage techniques provide a possibility to produce chemical pulps, which have the advantages of both mechanical pulp (high-yield pulp), and chemical pulp (good strength properties). At moderate concentration of Caro's acid used (3.0, 4.5% based on raw materials), three-stage technique has higher delignification selectivity than that of two-stage technique Three-stage techniques produced pulps of higher breaking length and burst factor than that produced by two-stage techniques. Tear factor of pulps produced by two-stage techniques has the superiority.
