使用浸渍法制备了一系列Co/SBA-16催化剂，并通过氮物理吸附、X射线衍射、氢程序升温还原、氢化学吸附和透射电镜技术对催化剂行了表征。研究表明，随着负载钴含量的增加，金属钴的分散度降低了，这是同Co3 O4晶粒增长和比表面积降低相一致的。 Co/SBA-16催化剂展示了高的一氧化碳转化率，低的C1选择性和高的C5+选择性，特别对柴油组分有高选择性。

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 Co3 O4 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.
