摘要：
Cobalt catalyst supported on hierarchical zeolite possessing a three different Si/Al ratio was studied in Fischer-Tropsch synthesis. The catalyst with Si/Al ratio of 60 was found to be superior to other catalysts in terms of better C5-18 selectivity and higher olefin/paraffin ratio due to smaller cobalt particles and larger number of acidic sites. While Co/Meso-ZSM120 catalyst with perfect crystal structure favored products to accessibility and prevented cobalt particles from being oxidized compared to that of amorphous support, resulting in the lowest deactivation rate and the lowest carbon content on the surface.
