Effects of NTA on the FTS activity and structure of Co species during the catalyst preparation were investigated to make clear the origin of its promoting effect. The FTS activity of the catalyst prepared from Co nitrate solution modified with NTA strongly depends on the calcination temperature. Higher FTS activities were obtained only when the catalyst was calcined at higher temperature. Diffuse reflectance FT-IR measurements showed that NTA-Co complex formed in the impregnation solution was interacted with Si-OH after impregnation, and preserved during calcinations step (around 523K), which leads to higher dispersion and higher reducibility after calcination.
