Abstract

Thermocatalytic decomposition of methane (TCD) is one of the most advanced process, which will meet the future demand and attractive route for COx free production of hydrogen. In this study, an attempt made using flame synthesized titanium nanorods as a catalyst support for nickel based catalyst for the hydrogen production. The comparison study between Ni/TiO2 and Ni/Flame synthesized TiO2 (Ni/F-TiO2) catalysts for hydrogen production using thermocatalytic decomposition of methane. The effect of nickel weight percentage (10%, 20%, 30% and 40wt %) and reaction temperature (650, 700, 750 and 800ºC) with Ni/ TiO2 and Ni/F-TiO2 catalysts were performed for hydrogen production studies at 54sccm flow rate of methane. It was observed that at 30wt% of Ni/ TiO2 and 30wt% of Ni/ F-TiO2 showed the maximum hydrogen production of 48 volume% and 55 volume % at 60min of reaction time at 700ºC. Before and after the reaction catalysts were characterized by the XRD, BET surface area, SEM and TEM analysis. Apart from hydrogen production carbon nanorods were observed with a diameter and length of 5-10nm and 0.25μm respectively for Ni/ TiO2 and for Ni/ F-TiO2 catalyst it was found to be 50-100nm and 0.5μm respectively.
