FIELD: chemical industry.

SUBSTANCE: inventions relate to the conversion of synthesis gas. A catalyst for the direct conversion of synthesis gas to produce liquid fuel is described, which contains a component Ⅰ and a component Ⅱ; these components Ⅰ and component Ⅱ are combined with each other by mechanical mixing; the active component of component Ⅰ is metal oxide, and component II is a molecular sieve with one-dimensional channels formed by ten-membered rings; the specified metal oxide is one, two or more of MnO_x, MnCr_yO_(x+1,5y), MnAl_yO_(x+1,5y), MnZr_yO_(x+2y), MnIn_yO_(x+1,5y), ZnO, ZnCr_yO_(1+1,5y), ZnAl_yO_(1+1,5y), ZnGa_yO_(1+1,5y), ZnIn_yO_(2+1,5y), CeO₂, CoAl_yO_(1+1,5y), FeAl_yO_(1+1,5y), Ga₂O₃, Bi₂O₃, In₂O₃, In_yAl_zMnO_{(x+1,5y+1,5z)}, In_yGa_zMnO_{(x+1,5y+1,5z)}; the range of values of the specified x is 1-3.5; the range of values of y is 0.1-10; the range of values of z is 0.1-10; the specific surface area of the specified MnO_x, ZnO, CeO₂, Ga₂O₃, Bi₂O₃, In₂O₃ is 1-100 m²/g; the specific surface area of the specified MnCr_yO_(x+1,5y), MnAl_yO_(x+1,5y), MnZr_yO_(x+2y), MnIn_yO_(x+1,5y), ZnCr_yO_(1+1,5y), ZnAl_yO_(1+1,5y), ZnGa_yO_(1+1,5y), ZnIn_yO_(2+1,5y), CoAl_yO_(1+1,5y), FeAl_yO_(1+1,5y), In_yAl_zMnO_{(x+1,5y+1,5z)}, In_yGa_zMnO_{(x+1,5y+1,5z)} is 5-150 m²/g; in this case, the specified molecular sieve is a molecular sieve with a topological structure of TON, AEL, MTT or MRE, and is one of SAPO-11, ZSM-23 or ZSM-48. A method for direct conversion of synthesis gas to obtain liquid fuel is described, in which a conversion reaction is carried out with synthesis gas as a raw material for the reaction under conditions of a stationary layer or a mobile layer, while the above-mentioned catalyst is used.

EFFECT: production of liquid fuel with a reduced content of aromatic compounds.
