Method for directly preparing aromatics from syngas

A method for preparing aromatics from syngas, comprising:

• a) contacting a raw material stream containing syngas with a catalyst in a reaction zone under reaction conditions sufficient to convert at least part of the raw material to obtain a reaction effluent;
• b) separating the reaction effluent to obtain at least a recycle stream containing gas-phase hydrocarbons having 1 to 4 carbon atoms and unconverted syngas and a liquid stream containing hydrocarbons having 5 or more carbon atoms;
• c) returning the recycle stream to the reaction zone;
• and
• d) separating aromatic products from the liquid stream, wherein the catalyst comprises at least one of an inertcontrol-confined highly dispersed metal oxide material, an acidic molecular sieve, and a graphite powder and a dispersant, wherein in the inertcontrol-confined highly dispersed metal oxide material, the inert carrier is at least one of silicon oxide and aluminum oxide, and the content of the metal oxide in terms of metal is less than or equal to 10% by mass, based on the weight of the inertcontrol-confined highly dispersed metal oxide material;
• and the acidic molecular sieve is selected from modified acidic ZSM-5 molecular sieve, modified acidic ZSM-11 molecular sieve and mixtures thereof.
