Abstract. Cobalt on alumina catalysts were prepared and tested in the partial oxidation of methane using dry feed at moderate gas temperatures (700–973 K) and atmospheric pressure. The effect of adding small amounts (1/15 molar ratio) of Ni, Fe, Cr, Re, Mn, W, Mo, V and Ta oxides was studied. The catalysts were prepared using incipient wetness impregnation followed by direct reduction of …
