FTS performances of the catalysts were tested in a continuous stirred tank reactor (CSTR). It is found that the increase of Si(P)/Si(B) ratio (Si(P)/Si(B)=0/25∼15/10) decreases the crystallite size of the catalysts, improves the surface basicity, enhances the reduction and carburization of the catalysts, and increases the activity of the catalyst. However, when Si(P)/Si(B) ratio is further increased (Si(P)/Si(B)=25/0), the catalyst exhibits a restrained reduction and carburization behavior, which may be attributed to the stronger metal-support interaction. Based on the present work, a catalyst with a suitable ratio of Si(P)/Si(B), for example Si(15)/Si(10) displays an optimal FTS performances.
