Cobalt Species

New type of Co-based catalyst was prepared using (CO)6Co2CC(COOH)2 as precursor supported on γ-Al2O3 support. 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.

Fischer Tropsch Synthesis

The effect of precursors of Co/γ-Al2O3 catalysts prepared from Co(NO3)2 and (CO)6Co2CC(COOH)2 on the Fischer-Tropsch synthesis (FTS) catalytic performance were investigated. All catalysts were characterised by TGA, BET, pore size distribution analysis and TEM techniques. For Aluminium-supported catalyst, the use of cobalt carbonyl cluster as cobalt precursor resulted in a higher activity and C5+ selectivities compared with the reference catalyst prepared from nitrate at low reaction temperature. The activities can be correlated with the zero valent cobalt metal exist on the support. The chain growth attribute to well dispersed smaller metallic cobalt particles resulted from the partial removal of terminal carbonyls at 150°C.
