| 摘 要： | 采用BET、元素分析、ICP和离子色谱等手段对工业叠合醚化保护床失活催化剂进行了研究。结果表明，保护床催化剂失活的主要原因是原料中的有机碱性氮化物引起的树脂催化剂交换容量的损失。失活催化剂经酸交换，约95%的酸交换容量能够得到恢复，其对醚化反应的活性接近新鲜催化剂的水平。

| Abstract: | Deactivated dimerization-etherification catalyst in the protective bed was characterized by BET,elemental analysis,ICP and ion chromarograph.It was found that loss of exchange capacity of the resin catalyst caused by basic nitrates was the main cause behind the deactivation.About 95% of the exchange capacity was restored with acid exchange,with activity of the regenerated catalyst close to that of fresh catalyst. |

| Keywords: | dimerization-etherification catalyst protective bed resin catalyst deactivation regeneration |
