Hydrogen production over ternary supported Ni/Al2O3-clinoptilolite-CeO2 nanocatalyst via CH4/CO2 reforming: Influence of support composition

In this paper the effect of Al2O3-clinoptilolite-CeO2 support with different Al2O3 and clinoptilolite contents on the Ni-based nanocatalyst are studied and tried to reduce process costs by replacing Al2O3 with clinoptilolite. The results of the nanocatalysts characterizations showed that, increasing the Al2O3 content decreases the NiO crystallites and particles size and improve specific surface area and surface morphology. The prepared nanocatalyst with content of 90% Al2O3 showed the highest feed conversion and products yield. However, the Ni/Al60-Cl30-Ce10 nanocatalyst had results much similar to superior sample and reduced 30 wt% of amount of Al2O3 and consequently decreased cost of catalyst preparation.328
