| Abstract: | Various Co-ZSM-5 zeolites which are modified by Si,P and B were prepared and the catalytic performance of ethane ammoxidation was investigated.The results showed that the Co-ZSM-5 zeolite with the 1.0 wt.% B loading has better catalytic performance for ethane ammoxidation.Combining the results of physical and chemical characterization,it is supposed that the α-type Co2＋ is the main activity center for ethane ammoxidation. |
