Ni/γ-Al2O3, Ni/Y-zeolite, and Ni/H-ZSM-5 catalysts were prepared using the incipient wetness impregnation method. Their catalytic performance in dry reforming of methane was studied. The fresh and used catalysts and deposited carbon were characterized using H2 temperature-programmed reduction, temperature-programmed oxidation, N2 adsorption-desorption, X-ray diffraction, and thermogravimetric analysis. The H-ZSM-5-supported Ni catalyst proved to be more stable than the other two catalysts, as it had the lowest carbon deposition
20% iron catalysts supported on combined alumina and silica through different proportions (Al2O3:SiO2:
100:0.00, 90.0:10.0, 80.0:20.0 and 0.0:100.0) were tested for the catalytic…
A novel approach to the in situ regeneration of a spent alumina-supported cobalt–iron
catalyst for catalytic methane decomposition is reported in this work. The spent catalyst was
