Development of Higher Stable Ni/MgO Catalyst for CO2 Reforming of Methane

Abstract

Abstract: Methane reforming by carbon dioxide has been studied over Ni/MgOcatalysts prepared by two impregnation methods which were common and promoted with support salt(magnesia salt). The catalysts were characterized by TPR, TPD, TPOand TPMC(temperature programmed methane decomposition to carbon deposition) techniques. The promoted catalyst exhibited a higher ability to adsorb CO₂ and lower ability of CH₄ decomposition. Therefore the carbon formation was inhibited and the catalyst stability was increased more.

Key words: CH₄ reforming by CO₂, Promoted impregnation by support salt, Ni-based catalysts
