BAGASSE is one of the potential raw materials for pulp in Egypt. So, our target is to improve the chemical properties of Kraft pulp using yield- increasing additives as anthraquinone (AQ), polysulfide (PS) and sodium borohydride (NaBH4). The effect of the bagasse to liquor ratio B/L ratio was also examined. The yield gains for AQ, PS, NaBH4, AQ-PS and AQ-NaBH4 were 4.73%, 6.46%, 2.99%, 12.15% and 4.05%, respectively for 1:4 B/L ratio. While the yield gains at 1:10 B/L ratio were 1.42%, 2.65%, 5.2%, 6.9% and 5.3%, respectively. Combination of AQ-PS gave synergistic effect. AQ, NaBH4 and AQ-NaBH4 reduced the kappa number by 7%, 14%, 9%, 4.48%, 40.3% and 5.95% for 1:4 and 1:10 B/L ratios, respectively. More dissolution of lignin was promoted at higher B/L ratio. All additives preserved the carbohydrate yield more than the Kraft one, and showed higher delignification selectivity except for PS.
