NOVELTY - A selective preparation of propylene and clean methanol gasoline is processed by carrying out catalytic conversion of methanol and zeolite socony mobil (ZSM) 11 multilevel porous material inserted in nanorod as catalyst active component in circulating fluidized bed reaction and regenerating device to obtain high-octane gasoline and propylene, i.e. adding low-carbon olefin methanol, transferring to double-arc bottom turbulent bed reactor (3), carrying out reaction, conveying oil and gas to conveying bed reactor (12), and settling reaction to separate reaction gas and catalyst.    USE - Selective preparation of propylene and clean methanol gasoline (claimed).    ADVANTAGE - The process has high value-added product, product yield, octane gasoline, and propylene selectivity, improves gas-solid contact efficiency, reduces propylene secondary reaction, and adjusts reaction temperature.    DETAILED DESCRIPTION - A selective preparation of propylene and clean methanol gasoline is processed by carrying out catalytic conversion of methanol and zeolite socony mobil (ZSM) 11 multilevel porous material inserted in nanorod as catalyst active component in circulating fluidized bed reaction and regenerating device to obtain high-octane gasoline and propylene, i.e. adding low-carbon olefin methanol in feeding ring pipe (1), transferring to double-arc bottom turbulent bed reactor through lifting pipe outlet which by loop has downward reaction direction, spraying feed in middle of double-arc bottom turbulent fluidized bed reactor in axial direction using feed-in injector nozzle to contact methanol with catalyst and carry out reaction at 300-500 degrees C for 2-5 s, conveying oil and gas from turbulent reactor to conveying bed reactor through upper diameter of turbulent reactor connected with conveying bed reactor outlet in which gas has 1-3 s residence time, settling reaction system in settling vessel (10) on top of conveying bed reactor to separate reaction gas and catalyst by cyclone separator, removing reaction gas (8) on top of settling vessel, regenerating catalyst using air (6) in regenerator (7) through inclined pipe (9), recycling regenerated catalyst in turbulent reactor through inclined lifting pipe (5), and raising lifting medium (4) and catalyst to turbulent reactor in which pre-lifting pipe (2) outlet is set on highest cross section of feed pipe nozzle outlet.
