Abstract: C1–C18 mixed alcohols can be synthesized from syngas over 15%Co-0.01%K-2%Zr/AC1 catalyst. Aactivated carbon AC1 from coconut shell had abundant oxygen-containing groups, which influenced Co phases and led to the higher selectivity for alcohols. K increased the alcohol selectivity, and Zr enhanced the catalyst activity.

Key words: activated carbon, cobalt, cobalt carbide, mixed high alcohols, oxygen-containing group, Fischer-Tropsch synthesis
