ABSTRACT
Fischer-Tropsch synthesis (FTS) is a reaction that converts coal, natural gas, or biomass-derived syngas into long-chain hydrocarbons. This process has gained increasing attention recently, due to limited petroleum resources and increasing oil price.1 Cobalt-based catalysts are widely used and studied. They offer low application temperatures, high selectivities for C5+ products, and low water-gas shift activity.2-6 The active sites for FTS are known to be situated on metallic cobalt phase; therefore, the catalytic activity is a function of both dispersion and cobalt reducibility.5,7,8 In order to improve dispersion of cobalt species, cobalt precursors are preferentially dispersed on porous materials such as SiO2,9 Al2O3,10 and TiO2.11
