Abstract
Methanation of syngas
is a possible way to produce synthetic natural gas. Ni has been proven to be a
good and cost-effective catalyst for this reaction. Here we have synthesized
Ni/MgO catalyst using mesoporous magnesium carbonate (MMC) as a precursor.
Addition of Al<sub>2</sub>O<sub>3</sub> and SiO<sub>2</sub> to MMC were made
and the different MMC based materials were then impregnated with Ni(NO<sub>3</sub>)<sub>2</sub>
and calcined to generate the catalysts. Addition of Al<sub>2</sub>O<sub>3</sub>
showed an improvement in the catalytic performance compared to the NiO/MgO
catalyst. The catalyst containing Al<sub>2</sub>O<sub>3</sub> had a CO
conversion close to 100 % at 350 °C and a high selectivity and yield for CH<sub>4</sub>.
The better performance of the aluminum containing catalyst was believed to be an
effect of a better dispersion of Ni at the surface of the catalyst<br>
