Abstract: A catalyst, including a molecular sieve carrier and an active component. The active component includes: iron, manganese, copper, and a basic promoter potassium. The molecular sieve carrier is a cerium salt and/or praseodymium salt modified-aluminosilicate molecular sieve carrier and/or silica-rich molecular sieve carrier. A method for preparing a catalyst for Fischer-Tropsch synthesis, includes: 1) fully dissolving a ferric salt, a manganese salt, a copper salt, and an alkali or a salt containing potassium element in water to yield an aqueous solution, stirring and adding sodium lauryl sulfate to the aqueous solution, and continuing stirring to yield a uniform solution; and impregnating a modified molecular sieve in the uniform solution to yield a mixed solution; and 2) drying and calcining the mixed solution to yield the catalyst.

Abstract: A method for recycling exhaust gas from Fischer-Tropsch synthesis. The method includes: 1) introducing raw gas to a shift reactor to conduct a water-gas shift reaction, and collecting shift gas; 2) introducing the shift gas to a Fischer-Tropsch synthesis device to yield a hydrocarbon fuel and exhaust gas, returning part of the exhaust gas as recycle gas; 3) introducing another part of the exhaust gas to a methanation reactor, allowing a methanation reaction to happen between the part of the exhaust gas and water vapor; 4) introducing a mixed gas product from the methanation reaction to a methane reforming reactor; 5) transporting the hydrogen and carbon monoxide resulting from the methane reforming reaction to a gas separator, separating the hydrogen and obtaining a mixed gas including carbon dioxide; and 6) returning the mixed gas including carbon dioxide to the methane reforming reactor.
