摘要
The study focused on synthesis of cobalt on cobalt-aluminate catalyst in one-pot via the solvothermal process. The obtained catalysts apparently exhibited higher activities than that prepared from the conventional solvothermal-derived alumina-supported cobalt catalyst without any changes in product selectivity during methanation. Enhanced activities can be attributed to the smaller amount of non-reducible cobalt-aluminate formed (at temperature <800 degrees C. Increased Co/Al molar ratios (1.0 and 2.0) also resulted in increased activities whereas the holding time during solvothermal synthesis had only little effect. (C) 2008 Elsevier B.V.
