摘要(Abstract)：

设计煤制活性炭的工艺流程，以探索贵州典型煤种制活性炭的可行性。以贵州无烟煤、烟煤及二者混合物为原料，经除灰、炭化后以水蒸汽为活化剂进行活化制活性炭，考察了活化温度、活化时间、水蒸汽流量及水蒸汽压力对活性炭亚甲蓝吸附值的影响，发现所制备活性炭的亚甲蓝吸附值随各因素的变化均存在极大值点，从而确定了适宜的活化条件，无烟煤、烟煤、混合煤所制活性炭的最大亚甲蓝吸附值分别为209、159、223 mg×g^-1，比表面积分别为1 121.37、908.58、1 342.88 m²×g^-1，优于其他活性炭。实验结果也表明：贵州煤制活性炭存在协同效应，混合煤基活性炭具有最好的亚甲蓝吸附性能，且制备条件比单一煤基活性炭更加缓和。基于吸附理论建立了活化过程动力学，回归得到活化过程的速率参数；扫描电子显微镜（SEM）显示，混合煤基活性炭比单一煤基活性炭更加疏松，孔隙更加发达。
