Stabilities of zeolite-supported Ni catalysts for dry reforming of methane

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.

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.Figure optionsDownload as PowerPoint slide
