Catalytic performance of zirconium-modified Co/Al2O3 for Fischer-Tropsch synthesis

The addition of Zr inhibits the formation of CoAl2O4 and causes the increase of cobalt active site and reducibility for Co/Al2O3 catalyst, which enhances the activity and C5+ selectivity for Fischer-Tropsch synthesis. The olefin/paraffin ratio is found to increase.
