摘要：

Co based catalysts supported on silica from two different sources were tested in F T synthesis and characterized by ICP, H 2 TPD and FT IR. It was found that the Co catalyst supported on home made silica was superior to the commercial silica. One reason was that the latter had a higher content of Na impurity, which was harmful to the catalytic activity owing to its alkaline effect. The other one might be that the silica source exerted an unfavorable effect on metal dispersion. A maximum C 5+ yield of 140g/Nm 3 (2H 2+CO) was obtained over Co/Si(3).
