Thermo Catalytic Decomposition of Methane Using Ni/SBA-15 catalyst was tested in a fixed bed reactor to simultaneously produce hydrogen and carbon nanotubes. SBA-15 nano catalysts were successfully been synthesized using p123, tetraethyl ortho silicate and Ni (NO3)2.6H2O as template, silica source and Nickel nano particle precursors respectively under acidic hydrothermal conditions. The BET surface area, pore size distribution and low angle X-ray Diffraction (XRD) studies revealed that the retention of hexagonally ordered behaviour in the catalysts. Wide angle XRD study divulged the crystalline behaviour of Nickel oxide species and these Nickel oxide species are in nano range. The catalytic activity experiments were preceded by blank tests intended to ascertain that the reaction did not take place to an appreciable extent in the absence of the catalyst. With SBA-15 alone and Ni alone reaction has not been taken place. Even with 50Ni-SBA-15 and 70Ni-SBA-15 catalysts reaction was not occurred. Only low loading Ni-SBA-15 catalyst was found to be active towards the conversion of methane into the corresponding hydrogen. Among all other catalysts, 30Ni-SBA-15 we observed to produce high yield of hydrogen produced 20% to 50% of H2 at a moderate temperature of 1123 K (850
The carbon nanorods (CNR's) were synthesized using flame reactor with diffusion burner. The growth of carbon nanorods in presence and absence of catalyst has been studied. The role of ferrocene as catalyst in the synthesis of carbon nanorods was investigated using a Flame Reactor at different oxygen to fuel ratios. The fuel used over here is acetylene. The fuel i.e., acetylene to oxygen ratio is also optimized to produce the carbon nanorods in presence of cataylst. The carbon nanorods showed a very good result with increasing yield and decreasing diameter with the use of catalyst. The morphology, purity and crystal structural characterization of CNR's was carried out using scanning electron microscopy, transmission electron microscopy and X-ray diffraction. From the analysis it was observed that in the presence of ferrocene, the density of CNR's increased with variable lengths between 10
