CATALYST FOR SYNTHESIS OF AROMATIC HYDROCARBONS AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2020 - IPC B01J29/06 B01J21/04 B01J23/06 B01J29/40 B01J37/04 C07C1/04 C07C15/00 

FIELD: chemistry.

SUBSTANCE: disclosed is a catalyst for synthesis of aromatic hydrocarbons, a method for production thereof and a method for synthesis of aromatic hydrocarbons directly from synthesis gas using said catalyst. Disclosed catalyst comprises particles of an acidic molecular sieve and particles of coprecipitated zinc oxide-aluminium, in which said particles of coprecipitated zinc oxide-aluminium additionally contain other metals; wherein said other metals include at least one metal selected from the group consisting of zirconium, copper, platinum, palladium and chromium; where said other metals are added to said particles of coprecipitated zinc oxide aluminium for modification by impregnation. Weight ratio of particles of acid molecular sieve to particles of coprecipitated complex zinc-aluminium oxide ranges from 2:1 to 1:2. Acid molecular sieve is an acidic molecular sieve ZSM-5. Particles of the coprecipitated composite zinc-aluminium oxide are obtained by forming an aqueous solution with a salt containing zinc and aluminium, and then co-precipitation of metal ions of the salt containing zinc and aluminium, using an aqueous solution of the precipitating agent to obtain a precipitate, after which said residue is held, washed, dried and calcined. Said metals are added to said particles of coprecipitated zinc oxide aluminium for modification by impregnation. Then, the particles of the coprecipitated zinc-aluminium oxide are mixed with the particles of the acidic molecular sieve ZSM-5.

EFFECT: catalyst has relatively high selectivity with respect to aromatic hydrocarbons, particularly BTX, and stable operating characteristics.
