摘要：A cobalt-based Fischer-Tropsch synthesis catalyst coated with mesoporousmaterials and preparation method therefor are disclosed. The catalyst comprises a silicacarrier surface-loaded with an active component of cobalt and a selective promoter ofzirconium; the outside of the active component of cobalt and the selective promoter of

zirconium is coated with a mesoporous material shell layer. The preparation methodcomprises preparing silica carrier loaded with zirconium, preparing an initial cobalt-basedFischer-Tropsch synthesis catalyst on the silica carrier base, formulating a precursorsolution of mesoporous materials, then dipping, crystallizing, washing, drying andcalcining to obtain the cobalt-based Fischer-Tropsch synthesis catalyst coated withmesoporous materials. The active component is coated and protected by themesoporous material shell layer, the thickness of the shell layer is controllable, thecatalyst has long service life, high reactivity and good stability. The pore structure ofmesoporous materials provides a channel for diffusing CO and H2, the selectivity of C5 +is high and the selectivity of methane is low. The catalyst is specially applicable to slurrybubble column reactors or continuously stirred tank reactors.
