英文摘要: The catalytic performance of Fe/Si-2 and Fe-Mn/Si-2 catalysts for conversion of C2H6 with CO2 to C2H4 was examined in a continuous-flow and fixed-bed reactor. The results show that the Fe-Mn/Si-2 catalyst exhibits much better reaction activity and selectivity to C2H4 than those of the Fe/Si-2 catalyst. Furthermore, the coking-decoking behaviors of these catalysts were studied through TG. The catalytic performances of the catalysts after regeneration for conversion of C2H6 or dilute C2H6 in FCC off-gas with CO2 to C2H4 were also examined. The results show that both activity and selectivity of the Fe-Mn/Si-2 catalyst after regeneration reached the same level as those of the fresh catalyst, whereas it is difficult for the Fe/Si-2 catalyst to refresh its reaction behavior after regeneration.
