, 2007 以芦苇制浆黑液木质素为原料,利用K2CO3为活化剂通过化学活化制备出以微孔为主的大比表面积活性炭。考察了活化温度对所得活性炭BET比表面积、微孔体积以及中孔体积的影响。确定了800℃为制备大比表面积活性炭的最佳温度。800℃下所得活性炭的BET比表面积以及孔体积可分别达到1401m2/g和0.79ml/g。XRD显示活性炭中出现硅晶体。该活性炭在pH=7下能较好的吸附重金属Cr(VI),其最大吸附量可达54.23mg/g ...

Gongye shui chuli饱和活性炭热再生工艺具有适用性强、对吸附质没有选择性的优点，是工业处理中最常用的方法，但热再生过程中吸附质在活性炭内发生分解、聚合等反应，残余物沉积在孔隙中，造成堵塞，使热再生处理后的活性炭比表面积和孔容积下降。了解热再生过程残余物沉积的机理及关键影响因素，减少残余物沉积，最大化恢复活性炭的吸附性能是热再生的关键。简要介绍了活性炭热再生工艺及再生过程中残余物沉积的机制，重点综述了再生过程中单一和混合吸附质情况下残余物沉积的特点，以及吸附质和活性炭的物化性质与残余物沉积的关系，阐明了热再生温度、气氛 ...
