Catalytic performances of Co/SiO2 prepared through thermal decomposition for Fischer-Tropsch synthesis
热分解法制备的Co/SiO2催化剂上费-托合成反应性能

Cobalt based catalysts supported on amorphous SiO2 were prepared through thermal decomposition as well as incipient wetness impregnation.They were characterized by means of TG,XRD,TEM and TPR and used in Fischer-Tropsch(F-T) synthesis.The results indicated that Co/A200-I catalyst prepared by impregnation exhibits high F-T synthesis activity,though cobalt particles in it are in irregular shape.In comparison,the cobalt particles in Co/A200-D catalyst prepared through decomposition are in secondary spherical s...
