A study was undertaken of the regeneration of three activated carbons exhausted with ortho-chlorophenol. The regeneration process was carried out using liquid water at 623 K and 150 atm in the absence of oxygen. The efficiency of this procedure was analyzed by determining the rate and amount of ortho-chlorophenol adsorbed in successive adsorption-regeneration cycles. The present procedure showed a much greater efficiency than that reported for chemical and/or thermal regeneration. Effects of this regeneration on the adsorption kinetics, adsorption capacity and textural characteristics of the carbon were investigated. The increase in adsorption capacity of the regenerated carbon compared with that of the original carbon seems mainly due to the opening of porosity during the regeneration treatment.
对三种被邻氯苯酚耗尽的活性炭的再生进行了一项研究。再生过程是在无氧条件下，于623K和150个大气压下使用液态水进行的。通过测定连续吸附-再生循环中邻氯苯酚的吸附速率和吸附量来分析该程序的效率。本程序显示出比化学和/或热再生所报道的效率高得多。研究了这种再生对碳的吸附动力学、吸附容量和结构特性的影响。与原始碳相比，再生碳吸附容量的增加似乎主要是由于再生处理过程中孔隙的打开。
