Adsorption and Reaction Behavior over Co Catalysts Supported by Different Zirconia Polymorphs

Abstract

Abstract: CO and CO/H₂ adsorption and reaction behavior over Co catalysts with amorphous, tetragonal and monoclinic zirconia as the supports were characterized by FTIR, TPSR and Fisher-Tropsch synthesis. The results show that cobalt catalysts with different zirconia polymorphs as the supports exhibited various behavior of CO adsorption and reaction. For the Co catalyst supported on monoclinic zirconia, besides the multi terminal CO, bridged and tribridged CO appeared and were easily dissocia-(ted) at a high temperature, which resulted in the higher catalytic behavior and C⁺_<sub>5 selectivity in the case of CO hydrogenation. While for cobalt supported on tetragonal zirconia, the bridged CO was more stable and CO hydrogenation was relatively less active.

Key words: Zirconia, CO adsorption, TPSR, Fisher-Tropsch synthesis
