Gasoline and preparation method

The present invention provides a method for preparing and gasoline. The preparation method comprises the steps of: S1, the direct liquefaction of coal physical naphtha desulfurization and denitrification process, the product is purified; S2, the purified product was fractionated to give the product C6- and C7 + products; S3, the product was re-C7 + reforming reaction, to give a mixed aromatics; mixed aromatics were separated to obtain reformate gasoline blending product; and S4, in parts by weight, 40 to 51 parts by reforming gasoline blending product, 20 to 35 and 20 parts of a mixed C C6- to 30 parts of a product obtained by mixing gasoline. Physical desulfurization and denitrification process of the invention uses simple operation, low cost, and low power consumption advantages. In a specific weight ratio of the reformed gasoline blending product was mixed with the mixed C C6- product and help improve the gasoline octane number, and produce low emissions, high calorific value, high-quality gasoline.
