| Abstract: | The selective catalysis of ZSM-5 zeolite catalysts treated with steam at high temperature and modified by the cation before treated with steam or treated with steam before modified by the cation to the alkylation of toluene with ethylene was studied. It is found that the steam treatment is a good method to increase the active stability of ZSM-5 zeolite catalysts. The order of cation modification and steam treatment strongly influences the alkylation reaction. The acidity of ZSM-5 zeolite catalysts is characterized with TPD and IR. |
