Preparation of Ni-based metal monolithic catalysts and a study of their performance in methane reforming with CO2.
A series of Ni/SBA-15/Al(2)O(3)/FeCrAl metal monolithic catalysts with Ni loadings varying between 3 % and 16 % were prepared, and their structure was characterized by various techniques. The catalytic activity of the catalyst for methane reforming with CO(2) leading to synthesis gas was evaluated using a fixed-bed reactor. The results indicate good catalytic activity of the Ni/SBA-15/Al(2)O(3)/FeCrAl samples under the reaction conditions. The catalyst with a Ni loading of 8.0 % displays excellent activity and stability at 800 degrees C over 1400 h time on stream. After reaction, the hexagonal mesoporous structure of SBA-15 is still present and the pore walls of SBA-15 prevent the aggregation of nickel. Interactions between NiO, SBA-15, and the Al(2)O(3)/FeCrAl support modify the redox properties of the Ni/SBA-15/Al(2)O(3)/FeCrAl catalysts.
