摘　　要：探索了改性 β沸石催化剂在合成二苯胺过程中的失活原因 ,对催化剂的再生工艺进行了研究。结果表明 ,催化剂失活的主要原因是催化剂积碳和高分子副产物碱性氮化合物堵塞催化剂孔道 。The reasons for deactivation of modified β zeolite catalyst in the synthesis of diphenylamine were explored. The regeneration technic of deactivated catalyst was researched. The carbon deposition of the catalyst and the hole jam of the catalyst caused by the macromolecule nitrogen compound were the main cause of the catalyst deactivation. After regeneration, the catalyst activity and stability would come back to the level of fresh catalyst.
