NOVELTY - A methanol or dimethyl ether gasoline synthesizing method, involves generating hydrocarbons rich in gasoline component from methanol or dimethyl ether, and passing the liquid to flash column, gas-liquid separating tank and fractionating tower to separate 1-2C hydrocarbon, 3-4C hydrocarbon, light gasoline component, heavy gasoline component and water.    USE - Method for synthesizing methanol or dimethyl ether gasoline.    ADVANTAGE - The method enables synthesis of methanol or dimethyl ether gasoline in simple manner, with low energy consumption and provides yield of gasoline to 36-40% when refined methanol is utilized as reference and to 50-54% when dimethyl ether is utilized as reference.    DETAILED DESCRIPTION - A methanol or dimethyl ether gasoline synthesizing method, involves generating hydrocarbons rich in gasoline component from methanol or dimethyl ether, and passing the liquid to flash column, gas-liquid separating tank and fractionating tower to separate 1-2C hydrocarbon, 3-4C hydrocarbon, light gasoline component, heavy gasoline component and water. Light gasoline component is product efflux of water into sewage treatment unit. 1-2C hydrocarbons are added into hydrocarbon synthesis reactor pressurized by compressor. After aromatization, 3-4C hydrocarbons are mixed with heavy gasoline product directly, and added into transalkylation reactor, followed by adding the obtained product to flash column and discharging small amounts of 1-2C hydrocarbons and heavy gasoline components as by-product. HZSM-5 zeolite catalyst is treated with methanol or dimethyl ether raw material at 350-450 degrees C, pressure of 0.5-2 MPa, and weight hourly space velocity (WHSV) of 0.5-2.5 hour-1 to obtain hydrocarbon-rich gasoline component. Obtained reaction product is cooled to 50-300 degrees C using heat exchanger. Cooled product is passed into flash evaporation tower to separate gas-liquid phase, where gas phase contains 1-4C hydrocarbons and liquid phase contains 5C+ hydrocarbons and water. Gas-phase product is cooled by heat exchanger and copper hydrocarbons and 3-4C hydrocarbons are separated. Copper hydrocarbons are returned to gasoline synthesis reactor. 3-4C hydrocarbons are passed into liquefied gas aromatization reactor, and reacted at 400-600 degrees C and pressure of 0.1-2 MPa.
