    • Abstract

       

      By using catalysts of Co/Mg1−xNixO (x= 0, 0.03, 0.07, 0.15; 1 wt% Co each), we performed the dry reforming of methane. The catalysts were prepared by K ₂ CO ₃ co-precipitation from aqueous nickel nitrate hexahydrate and magnesium nitrate hexahydrate. Impregnation of cobalt(II) acetylacetonate onto MgO-NiO was then conducted. TEM, XRD, FTIR, XRF, XPS, and BET characterizations of the catalysts were carried out. Results showed that the catalysts were reduced at 700 ◦C by H ₂ prior to each reaction. CH ₄ and CO ₂ conversions at 900 ◦C of the catalysts after being tested for 200 h decreased in the arrange Co/Mg0.85Ni0.15O, Co/Mg0.93Ni0.07O, Co/Mg0.97Ni0.03 O, and Co/MgO. The highest H ₂ and CO selectivities were observed at a 1:1 CH ₄ :CO ₂ mole ratio. We further performed a dry reforming in the presence of low-concentration oxygen flow (1.25 Vol %) and found an increased CH ₄ conversion.
