Abstract
Coal combustion for power generation is a source of CO2 emission into the atmosphere. During that process, waste materials are formed such as cenospheres, which are a fraction of fly ashes. These cenospheres were applied as a catalyst support for the CO2 methanation reaction, which is a promising process for carbon dioxide utilization. Two series of catalysts were compared, a reference one based on the unmodified cenospheres, and a second based on the cenospheres modified by perforation. Nickel supported on Cenospheres nickel, or else nickel with Mg–Al mixed oxides, were prepared by solution combustion synthesis. Perforated cenospheres supporting Mg–Al mixed oxides led to a catalyst with significantly improved catalytic performance (88% at 300 °C) and selectivity to methane (>99% at 300 °C). In this work we evidence better development of the specific surface area, increased surface basicity, improved dispersion of nickel crystallites thanks to the presence of Mg–Al and enlarged number of basic centers at the surface.
