摘　　要：对受乙二醇污染的Parex工艺吸附剂的再生方法进行研究。结果表明 :添加质量分数为 3%活化剂的正丁醇对中毒吸附剂具有很好的再生能力。与新鲜吸附剂相比 ,再生吸附剂对PX的选择吸附活性达 98.1% 。The regeneration processes for Parex adsorbent polluted by ethylene glycol are studied. The results show that, the solution of 3% activator and 97% n -butyl alcohol has good regenerating ability to the toxic absorbent. In comparision with the fresh adsorbent, the adsorption selectivity of regenerant to PX reaches 98.1% which meets all the requirement of commercial application.
