Effects of Different Pretreatment Pressures on the Catalytic Performance of Catalyst Derived from (CO)₆Co₂CC(COOH)₂ for Fischer-Tropsch Synthesis

Abstract:

New type of Co-based catalyst was prepared using (CO)₆Co₂CC(COOH)₂ as precursor supported on γ-Al₂O₃support. The effects of pretreatment pressures on the catalysts properties and the F-T synthesis performance were investigated in details. Combined with TEM characterization technology, it was found that under different pretreatment pressures (0 MPa, 1.0 MPa, 2.0 MPa), the structure of carbonyl clusters underwent different changes. Moreover, the aggregation degree of cobalt species depends on the pretreated pressure applied. In addition, the catalytic performance of the cobalt carbonyl catalyst pretreated with different pressures was performed and both CO conversion and C₅⁺selectivity exhibited the order of Co₂/2MPa/Al₂O₃ > Co₂/1MPa/Al₂O₃ > Co₂/0MPa/Al₂O₃.
