NOVELTY - High-temperature Fischer-Tropsch synthesis oil is separated into high-temperature condensate, low-temperature condensate, and gaseous hydrocarbon. The gaseous hydrocarbon and high-temperature condensate are introduced into lifting tube reactor (I) and contacted with a catalyst to obtain oil mixture (I). Oil mixture (I) is separated into oil gas and catalyst, the separated catalyst is sent to fluidized bed reactor (I) and/or stripper, and the oil is passed to a product separator. The low-temperature condensate is also separated into catalyst and product.    USE - Catalytic processing of high-temperature Fischer-Tropsch synthesis oil (claimed).    ADVANTAGE - The method provides high propylene yield.    DETAILED DESCRIPTION - High-temperature Fischer-Tropsch synthesis oil is separated into high-temperature condensate, low-temperature condensate, and gaseous hydrocarbon. The gaseous hydrocarbon and high-temperature condensate are introduced into lifting tube reactor (I) and contacted with a catalyst to obtain oil mixture (I). Oil mixture (I) is separated into oil gas and catalyst, the separated catalyst is sent to fluidized bed reactor (I) and/or stripper, and the oil is passed to a product separator. The low-temperature condensate is introduced into lifting tube reactor (II) to obtain oil mixture (II). Mixture (II) is sent to fluidized bed (II) and/or stripper. The catalyst is separated and product is sent to a product separator. The catalyst contains less than 0.7 nm zeolite. An INDEPENDENT CLAIM is included for catalyst processing device consisting of lifting tube reactors (I,II), a fluidized bed reactor, a stripper, a precipitator, a regenerator, a catalyst heat exchanger, and a gas-solid separator connected to lifting tube reactor (I). The outlet of gas-solid separator is connected to the fluidized bed reactor whose bottom is connected with the stripper. The stripper is connected to a catalyst conveying line and regenerator. The lifting tube reactor is provided with a gas inlet and an outlet.
