The rapid growth of the world population has increased the need for energy day by day. Fossil fuels are non-renewable energy sources and increase carbon dioxide emissions. Researchers have focused on alternative renewable and clean energy sources. One of the key energy source is hydrogen. The steam reforming of biomass is an environmentally friendly and cost-competitive way of producing hydrogen. Acetic acid has been identified as one of the major organic acids in the product of biomass pyrolysis [1]. Production of syngas from steam reforming acetic acid is a highly complex process process with side reactions (R-1). Decarboxylation and coke formation reactions would also contribute to the product distributions and catalyst deactivation. Therefore, development of an efficient steam reforming catalyst is an important factor [2]. Cobalt, as an group VIII metal, is also employed as the active metallic phase in various steam reforming reactions. However, the development of cobalt catalyst has received less attention for acetic acid steam reforming due to reoxidation problem of metallic cobalt during steam reforming of organics [3]. Previous studies related to reforming reaction showed that bimetallic catalysts have synergytic effect on activity and coke minimization.
