抄録

A hierarchically spherical Co based zeolite catalyst with aggregated nanorods structure (simplified as Co/AN-Z) was prepared by an in-situ self-assembly crystallization route of Co/SBA-15 under hydrothermal synthesis environment. The obtained Co/AN-Z catalyst with uniformly sized zeolite microspheres with 0.5–1 μm was evaluated for improved Fischer-Tropsch synthesis (FTS) reaction activity and isoparaffin selectivity. The selectivities of isoparaffin and C_5-11 hydrocarbons were higher with a narrower product distribution as well as CH₄ and C₁₂₊ selectivities were lower on the Co/AN-Z catalyst than those on the commercial HZSM-5 supported Co catalyst (Co/HZSM-5) for FTS reaction. The demonstrated route of the hierarchically spherical Co based zeolite catalyst can be extended to synthesize bifunctional catalyst and expected to find a new approach for tandem reaction.
