Abstract:
PURPOSE: A method for manufacturing an iron catalyst is provided to reduce the amount of distilled water required for filtering and washing by remaining the adequate amount of sodium in the catalyst. CONSTITUTION: A method for manufacturing an iron catalyst includes the following: a mixed solution is prepared by mixing a ferric nitrate aqueous solution and a copper nitrate aqueous solution(S10); at least one of a sodium carbonate aqueous solution or a sodium hydroxide aqueous solution is added into the mixed solution to form precipitated slurry(S20); the precipitated slurry is washed and filtered based on distilled water(S30); fumed silica powder and a potassium carbonate solution are added into the precipitated slurry to be stirred(S40); the precipitated slurry passes through a sieve and is dried to form a powdered iron catalyst(S50); and the iron catalyst is dried and thermally treated(S60).
Abstract:
PURPOSE: A complex reactable Fischer-Tropsch(F-T) bubble column reactor is provided to simplify manufacturing facilities and to improve the yield of synthetic fuel by improving energy efficiency of the reactor. CONSTITUTION: A complex reactable F-T bubble column reactor includes a first dispersing unit(20a) and a second dispersing unit(20b). The first dispersing unit and the second dispersing unit define the inside of a bubble column reactor main body(10) such that two complex reaction regions are formed in the main body. A first reaction region(20a-1) is formed at the upper side of the first dispersing unit and implements a F-T reaction with Fe-catalyst. A second reaction region(20b-1) is formed at the upper side of the second dispersing unit and implements a F-T reaction with Fe/Co catalyst or Co catalyst. The F-T bubble column reactor reacts coal synthetic gas with catalyst contained in slurry to generate synthetic fuel.
Abstract:
A catalyst separation apparatus for an FT slurry bubble column reaction system is provided to produce synthetic fuel with a high purity by effectively removing an iron catalyst in synthetic fuel and increase the production efficiency of the synthetic fuel by separating the iron catalyst more promptly. A catalyst separation apparatus(100) for an FT slurry bubble column reaction system comprises: a separation tank(110) connected to an FT slurry bubble column reactor to receive synthetic fuel; a catalyst separating unit(130) adhered to an outer peripheral surface of the separation tank to adhere an iron catalyst contained in the synthetic fuel to an inner wall surface of the separation tank by magnetism; and a separation unit(120) transferring the iron catalyst adhered to the inner wall surface of the separation tank to the bottom of the separation tank to resupply the iron catalyst to the FT slurry bubble column reactor through an iron catalyst discharge pipe. The catalyst separating unit includes a magnet(131) and an insulating material(132). The separation unit includes a drive unit(121), a drive shaft, and a screw(122). The screw has a space part(122a) formed therein in the axial direction, and the screw is connected to the drive shaft through a support connected to the space part.
