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.
