Catalytic behaviour Ni/γ-Al2O3 microporous catalysts in the methane dry-reforming reaction

Two series of Ni/γ-Al2O3 catalysts with Ni content between 3.5 and 14 were prepared. In the first series, a γ-alumina support previously prepared was impregnated with Ni(NO3)2·6H2O (Merk) using an incipient wetness method and in the second, the Ni salt was incorporated into the precursor solution during the γ-alumina preparation. All the samples were characterised by XRD, DTA/TG, Nitrogen adsorption, CO-chemisorption, and tested by methane dry-reforming reaction experiments.
