Methane Decomposition to Hydrogen Over Zirconia-Supported Fe Catalysts-Effects of the Modified Support.

ABSTRACT: Methane decomposition is a promising route to synthesize CO_x -free hydrogen and carbon nanomaterials (CNM_s ). In this work, the impregnation method was employed for the preparation of the catalysts. Systematic investigations on the activity and stability of Fe-based catalysts were carried out in a packed-bed micro-activity reactor at 800 °C with a feed gas flow rate of 18 mL/min. The effect of doping Y₂ O₃ , MgO, SiO₂ and TiO₂ over ZrO₂ on the catalytic performance was also studied. BET revealed that the specific surface areas and pore volumes are increased after SiO₂ , TiO₂ , and Y₂ O₃ are added to ZrO₂ while MgO had a negative impact and hence a little decre
