采用绿液蒸煮与氧脱木素联合制浆工艺对稻草原料绿液法制浆进行了初步探索。研究结果表明，稻草原料采用绿液蒸煮，在用碱量16％（Na2O计）、硫化度20％左右、最高温度150℃不保温的蒸煮条件下，可得到卡伯值26的浆料。该浆料继续氧脱木素，在氢氧化钠用量2％～3％、氧压0．7MPa、最高温度110℃条件下，可将卡伯值降至10左右。绿液蒸煮浆料得率可达60％以上，氧脱木素段得率约90％，联合制浆得率55％以上。绿液与氧脱木素联合制浆工艺可将麦草原料中约65％75％的硅保留在浆料中，并且浆料的强度性能与常规碱法浆相近。

Pulping performance of rice straw by green liquor (GL) cooking combine with oxygen delignification was investigated. The results indicated that the pulp which Kappa number 26 were obtained under conditions of total titratable alkali of 16% (as Na20 on straw), sulfidity of 20% and highest temperature of 150℃. When the GL pulp was subject to oxygen delignification using alkali 2%-3%, the Kappa number decreased from 26 to around 10. The yields of green liquor cooking and oxygen delignification were above 60% and 90% respectively. Around 65%-73% of silica was kept in pulp and the physical properties of GL-O pulp were better than AP-AQ.
