Abstract: (57) Abstract: The invention relates to a method and an installation for producing a concentrate of aromatic hydrocarbons from light aliphatic hydrocarbons and from mixtures thereof with oxygenates. According to the method, an initial raw material is fed into two in-series-connected reaction units, a first unit and a second unit, with zeolite catalysts based on a pentasil group; the reaction units arc distinguished through the conditions for converting the hydrocarbons to aromatic hydrocarbons; a mixture obtained following the reaction units is separated into a liquid fraction and a gas fraction, and the gas fraction is fed to the inlet of the first and second reaction unit.
