FIELD: petrochemical process catalysts.
SUBSTANCE: catalyst preparation method comprises: mixing high-silica Pentasil ZSM-5-type zeolite in ammonium form with distilled water, zinc nitrate, aluminum hydroxide, and boric acid; evaporating resulting mass; molding granules; drying; and treating granules with laser emission at power 40-50 W in three passes across monolayer of catalyst granules at scanning rate 800-1000 mm/min.
EFFECT: increased yield of aromatic hydrocarbons.
