| 英文摘要 | Al 2 O 3 nano-sheet (Al 2 O 3 -CN) was synthesized under hydrothermal condition. The cobalt-based catalyst of 20% (mass fraction) was prepared by impregnation method and applied to Fischer-Tropsch synthesis. The Al 2 O 3 -CN (226 m 2 2 O 3 -C, 249 m 2 2 O 3 -CN has more narrow pore size distribution. Compared with Co 2 O 3 -C catalyst, Co 2 O 3 -CN catalyst showed higher reduction degree and more uniform cobalt particle size distribution after impregnation. Thus, Co 2 O 3 -CN catalyst exhibited higher CO conversion and lower methane selectivity. In order to further improve the catalytic performance of Co 2 O 3 -CN, Al 2 O 3 -CN was modified with ZrO 2 . The characterization results showed that with the increase of ZrO 2 , the specific surface of Al 2 O 3 -CN did not change significantly, and the pore volume and pore diameter increased. The cobalt particle size decreased and the number of active sites increased. Under the same reaction conditions, the CO conversion rate of catalysts modifield by ZrO 2 was further improved and selectivity of methane was decreased. |
