| 摘 要： | 对大雁和扎赉诺尔两种褐煤的超临界萃取焦渣在ＣＯ２中的活化性能以及活化前后对酚的吸附性能进行了研究,考察了半焦性质,活化条件等对数以酚吸附量的影响。研究表明,萃取焦渣与原煤相比具有较好的吸附性能,经ＣＯ２活化处理,其吸附能力可以明显得到改善。

| Abstract: | The activation and phenol sorption experiments were carried out to investigate the phenol sorption capacity on raw and CO 2 activated chars obtained at different conditions.The results indicated that the chars obtained from supercritical toluene extraction of lignites posses higher phenol sorption capacity than raw coal.By activated with CO 2,the phenol sorption capacity of char can be promoted greatly.The activated char obtained under certain conditions could be used in the place of commercial activated carbon. |
