| 英文摘要 | fe-doped mgal2o4 spinet catalyst of mgfe0.1al1.9o4 and supported catalyst of fe2o3-mgo/gamma-al2o3 for ethylbenzene dehydrogenation in the presence of co2 were studied by mossbauer spectroscopy (ms) combining with the partial reduction method in the presence of h-2, and the catalytic activity of the ferrous iron species was discussed. the results showed that the catalytic performance of fe3+ existing in spinel is superior to alpha-fe2o3, and the synergistic effect between fe2+ and fe3+ might indeed increase the catalytic activity since fe2+-o2- formed in the process of reduction has moderate basicity, which was more favorable for desorption of co2 compared with mg2+-o2-. the reduced mgfe0.1al1.9o4 containing fe2+ of around 25% exhibits much higher catalytic activity than unreduced catalyst, with improved styrene yield nearly 2 times to 45.0%. mgxfe1-xo as another ferrous iron species formed in the reduction process of fe2o3-mgo/gamma-al2o3 showed inconspicuously catalytic activity.
