摘　　要：研究了麦草氧碱制浆的最佳工艺条件。结果表明,氧碱制浆可以在比常规烧碱-AQ法节碱35%左右,蒸煮最高温度120℃的条件下,取得64.8%的粗浆得率。对纸浆进行全无氯漂白的结果证明,采用合适的螯合剂和漂白活化剂可以漂至较高的白度。The optimum condition of wheat straw oxygen-alkali pulping is studied in this paper.The unscreened pulp with64.7%yield can be produced when alkali dosage is35%lower than that of conventional NaOH-AQ process.The oxygen-alkali pulp can be bleached to high bright-ness through total chlorine free(TCF)bleaching technology by using suitable chelating and activated bleaching reagent.Meanwhile the oxygen-alkali pulping can decrease COD and residual alkali of black liquor effectively.
