Abstract:The shortage of wood resources has become one of the key bottlenecks restricting the development of China"s pulp and paper industry. To address the severe shortage of raw materials in the paper industry, it is essential to develop green and low-carbon pulping technologies based on agricultural straw resources. In this study, reed was used as raw material, and the green NACO pulping process was employed to systematically explore the effects of different cooking conditions on reed pulp and its paper properties. The results demonstrated that the optimal pulp performance was achieved under the following conditions: an alkali dosage of 18%, a temperature of 140°C, a holding time of 2 hours, and an initial oxygen pressure of 1.4 MPa. Under these conditions, the fine pulp yield was 44.88%, the brightness reached 31.5 %ISO, and the Kappa number was 24.5. The resulting paper exhibited excellent physical properties, with a tensile index of 53.98 N.m.g?1, a tear index of 4.48 mN.m2.g?1, a burst index of 3.30 kPa.m2.g?1, and a ring crush index of 6.53 N.m.g?1, all surpassing the performance of paper produced via the conventional oxy-alkali pulping process. |
