不同制备方法对Co/HZSM-5分子筛上性能的影响

Performance Effect on Co - HZSM -5 Zeolite of Different Preparation Method

不同制备方法对醛氨缩合催化剂Co/HZSM-5分子筛固相性质的影响较大,从而改变了催化性能。与浸渍法、机械混合法相比,采用离子交换法制备Co-ZSM-5分子筛催化剂具有较好的固相性质,极低的积炭量,较高的烷基吡啶收率。

The catalytic activity and structure of Co/HZSM - 5 zeolite under aldehyde - ammonia condensation were influenced by different preparation method. Compared with dipping and adherency method, Co - ZSM - 5 zeolite catalyst prepared by ion - exchange method had a high activity and yield of alkylpyridine but coke lower.
