    • A cobalt/zirconia-alumina catalyst in which small pores and large pores coexist by supporting cobalt as an active component on a zirconia-alumina support which comprises ZrO2 and Al2O3 and has a specific surface area by a coprecipitation process, thereby containing the cobalt in the support is provided, and a method for producing liquid hydrocarbons from syngas using the catalyst is provided. In a catalyst for Fischer-Tropsch reaction in which cobalt as an active component is supported on a support, the catalyst for Fischer-Tropsch reaction is characterized in that the catalyst is a catalyst in which cobalt as an active component is supported on a mixed support of zirconia and alumina containing Al2O3 and ZrO2, bimodal structures in which small pores(PS1) with a relatively small pore size and large pores(PS2) with a relatively large pore size coexist are formed in the catalyst, the small pores(PS1) ranges from 2 to 10 nm and the large pores(PS2) ranges from 10 to 200 nm, the ZrO2 is contained in the amount of 1 to 30 wt.% relative to the Al2O3, and the cobalt is contained in the amount of 5 to 40 wt.% relative to the total support. A method for producing liquid hydrocarbons from syngas comprises subjecting syngas to Fischer-Tropsch reaction in the presence of the catalyst for Fischer-Tropsch reaction to produce liquid hydrocarbons. Further, a specific surface of the carrier is 150 to 400 m^2/g and a specific surface of the catalyst is 100 to 300 m^2/g.
