The utility model discloses an aromatization catalytic reaction experimental device, which is used for researching evaluation and response of catalyst in the state of high temperature, high pressure and the like, evaluating and screening solid catalyst, researching catalyst performance, examining catalyst service life and regeneration regularity, and testing catalytic kinetic parameters. The device comprises a material supply unit; the material supply unit is connected with a dehydration and desulfuration unit through a pipeline; the pipeline led out from the dehydration and desulfuration unit is connected with a water supply unit and an aromatization catalytic reaction unit through a three-way valve respectively; a gas supply unit is connected to a pipeline at the inlet end of the aromatization catalytic reaction unit through a three-way valve; and the outlet end of the aromatization catalytic reaction is connected with a mixed aromatic gas-liquid separation system. The device can not only convert light alkanes into light aromatics, but also perform catalytic steam activation treatment and catalytic deactivation-regeneration reaction, and has the advantages of simple process, mature technology, small investment and easy achievement.
