Abstract
A method for preparing aromatics from syngas, which includes 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 includes at least one of an inert carrier-confined highly dispersed metal oxide material, an acidic molecular sieve, and, optionally, graphite powder and a dispersant.
