摘　　要：文章采用NH4OH-KOH-AQ对麦草进行蒸煮,系统研究了蒸煮液用量和配比、液固比、蒸煮最高温度、升温时间和保温时间对蒸煮效果的影响,继而确定了适宜工艺条件。结果表明,该蒸煮体系对麦草木素的脱除率达到85%,纸浆得率为49.65%。Wheat straw trials were carried out with NH4OH-KOH in the presence of anthraquinone. The operating conditions, such as the composition of the cooking liquor, the liquid to wheat straw ratio, the maximum cooking temperature and the cooking time at the maximum temperature during the pulping process were investigated systematically to establish optimal pulping conditions that can potentially eliminate problems with the production of black liquor. The experimental results indicated that this pulping process is particularly well suited for the pulping of wheat straw, where the percentage delignification was 90 %, and the pulp yield was 48.12%.
