Effect of Supports on Methane Decomposition over Supported Ni-Catalysts
Abstract:
The activities of Ni catalysts with different supports in methane decomposition have been studied.The activity order of the catalysts is Ni/SiO2 >Ni/MgO-Al2O3 >Ni/CaO-Al2O3 >Ni/α-Al2O3 and the interaction between Ni and the support is in the order of Ni/SiO2 2O3 2O3 2O3.It is thus concluded that the weaker the interaction between Ni and support,the higher the activity of the catalyst.It was also found that the activity of the silica supported Ni-catalyst was increased with increase in its average pore radius and predominance pore radius.
