Hydrogen is an attractive alternative source of the future need. It could be produced from the diverse sources and is used for a transport fuel which chiefly alliance with fuel cells. The crucial challenge for hydrogen production is reducing the price of production technologies to make the ensuing hydrogen price economical with conventional fuels. Thermocatalytic decomposition (TCD) of methane is one of the most advantageous technique which will meet the future demand, hence an eye-catching way for producing hydrogen with COx free environment. The present study deals with the production of hydrogen with 10 wt% of Pd impregnated in commercially available activated carbon and carbon black catalysts (samples coded as Pd10/AC and Pd10/CB, respectively). These combined catalysts were not attempted by previous studies. Pure form of hydrogen is produced at 850° C and volume hourly space velocity (VHSV) of 1.62 L/h g on the activity of both the catalysts. The analysis (X-ray diffraction (XRD)) of the catalysts reveals moderately crystalline peaks of Pd, which may be responsible for the increase in catalytic life along with formation of carbon nanotubes. The activity of carbon black is sustainable for a longer time when compared to that of activated carbon, which has been confirmed by life time studies (850° C and 54 SCCM of methane).
