ABSTRACT: Two of zeolites such as Hβ and HY, and mesoporous HMCM-41 were used as supports to immobilize AlCl3 for the investigation of the isomerization of endo-tetrahydrodicyclopentadiene (endo-TCD). The dependences of porous structure and surface acidity of the AlCl3 immobilized catalysts on the activity and selectivity were studied. Based on characterization studies, both the large pore diameter and strong acid sites of the supported catalysts contributed to the high activities in the endo-TCD conversion. And specifically the stronger Lewis acid sites seems to be responsible for the higher selectivity onto exo-TCD, and the stronger Br?nsted acid sites were crucial to the formation of adamantane through the further isomerization of exo-TCD.
