Carbon Nanotubes Synthesis by Chemical Vapor Deposition of Methane over Zn – Fe Mixed Catalysts Supported on Alumina
Carbon nanotubes were synthesized over a series of Zn-containing Fe/alumina catalysts by chemical vapor deposition method at two reaction temperatures of 850 and 950 °C using methane as a carbon source. Catalysts were synthesized by keeping Fe concentration constant and varying Zn concentration to study the effects of Zn. The catalysts were characterized using X – ray powder diffraction and N2 ...
متن کاملEffect of K2O on the catalytic performance of Ni catalysts supported on nanocrystalline Al2O3 in CO2 reforming of methane
CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...

متن کاملSurface Reaction Kinetics of Steam- and CO2-Reforming as Well as Oxidation of Methane over Nickel-Based Catalysts
An experimental and kinetic modeling study on the Ni-catalyzed conversion of methane under oxidative and reforming conditions is presented. The numerical model is based on a surface reaction mechanism consisting of 52 elementary-step like reactions with 14 surface and six gas-phase species. Reactions for the conversion of methane with oxygen, steam, and CO2 as well as methanation, water-gas shi...
متن کاملKinetic comparison of Ni/Al2O3 and Ni/MgO-Al2O3 nano structure catalysts in CO2 reforming of methane
The kinetic characteristics of the Ni/Al2O3 and Ni/MgO-Al2O3 catalysts were investigated in CO2 reforming of methane (CRM). The reaction orders (α and β) and the rate constant (k) were calculated using the non-linear regression analysis, in which the sum of the squared differences of calculated and experimental CO2 reforming of m...
