Development of higher stable Ni/MgO catalyst for CO2 reforming of methane

Abstract

Methane reforming by carbon dioxide has been studied over Ni/MgO catalysts prepared by two impregnation methods which were common and promoted with support salt (magnesia salt). The catalysts were characterized by TPR, TPD, TPO and 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.
