摘　　要：为保证金属氯化物吸附剂长期使用性能的稳定性,同时减缓因与氨气反应出现膨胀结块而导致的吸附性能的衰减,本文以氯化钙、膨胀石墨和木屑为原料,基于控制容积法测定吸附量,并通过正交实验的方法分析了浸溃用氯化钙溶液浓度、木屑与石墨质量比、炭化活化时间和炭化活化温度因素对复合吸附剂循环吸附量的影响。实验结果表明:配制氯化钙复合吸附剂最佳水平为浸渍的ω(CaCl_2)为0.2,木屑膨胀石墨质量比为4:1,炭化活化温度为500℃,活化时间为1.75 h。In order to guarantee the stability of the metal chloride adsorbent long-term using perfor- mance and reduce performance attenuation by reaction with ammonia appear expand agglomerate adsorption. Based on the control volume method, the calcium chloride, expanded graphite and sawdust were used as raw material in this study, the determination of the adsorption quantity and analyzed by using the method of orthogonal experiment impregnated with calcium chloride solution concentration, sawdust and graphite mass ratio, carbonization and activation time and activation carbonization temperature influences on composite adsorbent adsorption cycle. Experimental results show that the compound calcium chloride compound adsorbent optimal levels is impregnated calcium chloride solution concentration is 20%, sawdust expanded graphite quality ratio is 4：1, carbonization and activation temperature is 500~C, activation time is 1.75 h.
