Abstract

Abstract: The Co-La-Zr/AC catalyst reduced at 703 K showed good activity for CO hydroge nat ion to higher alcohols under the typical conditions of FT synthesis. Co2C spec ie s, which may play an important role in the synthesis of higher alcohols, were de tected by XRD in the used catalyst. The reduction temperature affects both the c obalt dispersion and formation of Co2C species.

Key words: cobalt catalyst, Fischer-Tropsch synthesis, reduction temperature, higher alcohol, cobalt carbide
