Co/SBA-16：Highly selective Fischer-Tropsch synthesis catalyst towards diesel fraction

A series of Co/SBA-16 catalysts were prepared by the incipient wetness impregnation method and characterized with N₂ physisorption，X-ray diffraction，H₂-temperature programmed reduction，hydrogen chemisorption and transmission electron microscopy techniques. It was found that the Co⁰ dispersion decreased with increasing cobalt loading，being consistent with the increase of Co₃O₄ crystallite sizes and the decrease of BET surface area. The Co/SBA-16 catalysts show high CO conversion，low C₁ selectivity，high C₅₊ hydrocarbon selectivity，and especially high selectivity towards diesel fraction.
