Abstract Activated carbons were prepared from spent mushroom compost using H3PO4 as activating agent. The effects of temperature (°C), impregnant ratio (H3PO4/biomass) and time (min) were determined by using Response Surface Methodology. The micropore area is above 75% of the total surface area. The activated carbon which has the maximum adsorption capacity with the largest specific surface area (1419.108 m2/g) was produced at the experimental conditions T = 450 °C, IR = 3.5:1 g/g and t = 50 min. The maximum activated carbon yield (56.2%) was obtained at 350 °C with an impregnant ratio of 1.5:1 g/g for 30 min.

用废蘑菇堆肥生产活性炭的统计模型

摘要 以H3PO4 为活化剂，用废弃的蘑菇堆肥制备活性炭。温度 (°C)、浸渍剂比 (H3PO4/生物量) 和时间 (min) 的影响通过使用响应面方法确定。微孔面积占总表面积的 75% 以上。在实验条件 T = 450 °C、IR = 3.5:1 g/g 和 t = 50 min 下，生产出具有最大吸附容量和最大比表面积 (1419.108 m2/g) 的活性炭。在 350 °C 下以 1.5:1 g/g 的浸渍比 30 分钟获得最大的活性炭产率 (56.2%)。
