Abstract
Ni/γ-Al 2 O 3 , 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 H 2 temperature-programmed reduction, temperature-programmed oxidation, N 2 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. In dry reforming of methane, the Ni catalyst supported on H-ZSM-5 zeolite was found to be more stable than those supported on alumina or Y-zeolite.
