| 摘要: |
In this article, catalytic decomposition of methane for hydrogen production
over several domestic commercial activated carbons was performed at a fixed bed
reactor. The effects of the textural properties and surface chemistry of the activated
carbon on its catalytic performance in methane decomposition were investigated;
furthermore, the correlation between these properties and the catalytic performance
is studied as well. The results show that the initial rate of methane decomposition has
no correlation to the surface area of the activated carbon, which indicates that only a
portion of the entire surface is active for methane decomposition. On the other hand,
the correlation between the total amount of methane conversion during the process
and the pore volume of the activated carbon is nearly linear, because the bigger pore
volume can accommodate more carbon deposition from methane decomposition, while
it has no relation to the micropore volume of the activated carbon. The oxygenated
functional groups of the activated carbon mainly decompose to CO and CO2 during
the temperature-programmed desorption process and the concentration of these groups
has a certain relation to the initial rate of methane decomposition. |
