Active Co/SiO2 catalysts prepared from mixing precursors for slurry phase Fischer-Tropsch synthesis

The catalysts prepared by mixing impregnation of cobalt (II) nitrate and co balt (II) acetate displayed high activity. X-ray diffraction indicated that highly dispersed cobalt metal was the main active site on the catalyst pre pared by mixing impregnation method. The metal reduced from cobalt nitrate promoted the reduction of Co2+ to metallic state in cobalt acetate by H-2 s pillover mechanism during catalyst reduction process.
