FIELD: technological processes.
SUBSTANCE: invention relates to catalytic processing of liquefied hydrocarbon gases and can be used in petrochemical industry. Invention relates to catalytic aromatization of hydrocarbons C3-C4, including a recuperative heat exchanger, a heater, at least two catalytic reactors operating alternatively in the raw material processing mode and regenerating the catalyst, as well as a catalyst separation unit located on the catalyst feed line. Each reactor is equipped with at least two catalytic sections including a catalyst layer and a distribution device with a heated methane feed line, on which there is a heater provided with a fuel supply line and a heated natural gas supply line, the catalyst separation unit is equipped with a methane recycling system comprising a gas separation unit provided with a methane feed line which is connected to feed and natural gas feed lines, and is also equipped with lines supplying non-converted components of raw material to feed line, output of aromatic hydrocarbons and gaseous processing products.
EFFECT: high output of aromatic hydrocarbons and high inter-regeneration period.
