FIELD: petroleum chemistry.
SUBSTANCE: claimed method includes purification of naphthalene-containing cuts from unsaturated compounds by catalytic polymerization followed by isolation of high purity naphthalene. Polymerization is carried out in presence of aluminum-cobalt-molybdenum catalyst, containing (mass %): cobalt oxide (CoO) 2.0-6.0 and molybdenum trioxide (MoO3) on carrier: Y-Al2O3 under pressure up to 0.6 MPa, at temperature of 180-200°C for 1-10 hours.
EFFECT: increased naphthalene yield.
