    • The thermocatalytic decomposition of methane is an environmentally attractive approach to CO2-free production of hydrogen. A fluidized bed reactor made of quartz with 0.055 m I.D. and 0.65 m in height was selected for the thermocatalytic decomposition. Carbon black was used as the catalyst for decomposition of methane. So, carbon black (DCC-N330) is used as catalyst. The methane decomposition reaction was operated at the temperature range of 850-900 oC, catalyst loading range of 50-200 g, methane gas velocity of 1.0 Umf – 3.0 Umf and the operating pressure of 1.0 atm.
    In this study, propane was added as reactant to make higher hydrogen yield. The comparison of methane only and the mixture of methane and propane in terms of operating conditions were made.
