Abstract: PURPOSE: A method and device for enhancement of reaction efficiency using air-lift and inverse fluidization in Fischer-Tropsch synthesis are provided to improve the synthetic reaction efficiency more than an existing single reactor. CONSTITUTION: A method and device for enhancement of reaction efficiency using air-lift and inverse fluidization in Fischer-Tropsch synthesis is as follows: A main reactor(10) is formed in the bottom end of a synthetic gas inlet(12). An ascending pipe(30) is neighbor-arranged in the main reactor. A first and second liquid circulation units(22,24) connect the main reactor and the ascending pipe. A first distributor(14) is installed in the bottom end of the main reactor, and disperses the synthetic gas to bubbles. A first sintered metal filter(16) is arranged under the first distributor inside of the main reactor, and divides a catalyst and liquid. A second distributor(34) disperses the unreacted gas and the byproduct gas to the uniform bubbles. The second sintered metal filter(36) is arranged under the second distributor, and divides the catalyst and liquid. An exhaust line(40) for the unreacted gas and the byproduct gas connects the top end of the main reactor and the bottom end of the ascending pipe. A first buffer container(42), a booster(44), and a second buffer container(46) are successively connected for high-pressurizing the unreacted gas and the byproduct gas. Water-level sensors(26) or thermocouples(28) are installed in the top end of the main reactor for sensing the water level of the liquid. A container(50) for filling catalyst and liquid mediator is connected with the liquid circulation unit via an opening/shutting valve(48).

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.
