| 英文摘要 | We report the simple preparation of the barium hexaaluminate (BaO center dot 6Al(2)O(3), BHA) with high surface area (BHA-HSA) (>100 m(2) g(-1)) through a coprecipitation method using carbon black as the hard template. Ni catalysts supported on BHA-HSA (Ni/BHA-HSA) with different NiO loadings (10, 20, and 40 wt%) were investigated in CO methanation for the production of synthetic natural gas (SNG). The CO methanation reaction was carried out at 0.1 and 3.0 MPa with a weight hourly space velocity of 30 000 mL g(-1) h(-1). It was found that Ni/BHA-HSA catalysts showed increased activity at low temperature (240-400 degrees C) compared with more conventional Ni/BHA catalysts with the same NiO loadings. A highest CH4 yield of 95.7% can be obtained over Ni/BHA-HSA (40 wt% of NiO loading) at 400 degrees C and 3.0 MPa, and a lifetime test shows that, at 500 degrees C and 3.0 MPa, it is more stable than Ni/BHA. The serious aggregation of Ni nanoparticles is the major reason for the deactivation of the latter. The work demonstrates that BHA-HSA can be effectively prepared using carbon black as the hard template and is more suitable as a Ni catalyst support for CO methanation. |
