    Abstract: An alumina-silica support is provided to secure high conversion rate of syngas, minimize production of by-products, and obtain long-term performance stability of the catalyst when performing a Fischer-Tropsch reaction by comprising SiO2 and Al2O3, and by allowing a particular specific surface area and small and large pores to be present in the support at the same time, a catalyst using the support is provided, and a method for production of liquid hydrocarbons from syngas using the catalyst is provided. As an alumina-silica support of a double layer structure which contains 1 to 80 wt.% of Al2O3 and 20 to 99 wt.% of SiO2, and which is formed by dispersing alumina particles onto a surface of silica, an alumina-silica support with a bimodal structure and a double layer structure is characterized in that a bimodal structure in which small pores(PS1) and large pores(PS2) with different pore sizes coexist is formed in the support, and a size of the small pores ranges 2 to 4 mum and a size of the large pores is more than 4 and less than or equal to 20 mum. The support has a total specific surface area of 150 to 400 m^2/g. The support maintains a ratio(S1/S2) ranging from 0.05 to 0.5, the ratio being a specific surface area(S1) of small pores ranged from 2 to 4 mum to a specific surface area(S2) of large pores ranged from 4 to 20 mum. A catalyst comprises 60 to 95 wt.% of the alumina-silica support onto which one or more transition metals selected from cobalt(Co), zirconium(Zr), ruthenium(Ru), rhenium(Re), and platinum(Pt) are supported.
