The invention discloses a reforming method for preparing high-quality aromatic hydrocarbons, which comprises the following steps of: heating a naphtha material, and introducing into a reactor; cooling products and performing high pressure separation; introducing reformed products into a stabilization tower for treatment; introducing generated oil obtained at the bottom of the tower into an extraction system; introducing the obtained extracted oil into a first recovery tower; introducing extracted products at the bottom into a second recovery tower; connecting the top of the second recovery tower with an aromatic hydrocarbon distillation system, and returning the extracted products at the bottom of the aromatic hydrocarbon distillation system to the extraction system; making the products pass through the extraction system, and introducing the obtained raffinate oil into a water washing system; introducing the extracted products into a raffinate oil distillation system; heating heavy raffinate oil extracted from the bottom of the tower by using a heating device, introducing into another reactor for reaction, and extracting light raffinate oil on the top of the tower; and cooling reaction products and introducing into a high pressure separator. The reforming method for preparing the high-quality aromatic hydrocarbons has the advantage that: the treatment capacity, the liquid yield, the yield of the aromatic hydrocarbons and the hydrogen output are greatly improved.
