<P>PROBLEM TO BE SOLVED: To provide a method for producing a conjugated diolefin in a high yield and stably, which can maintain the temperature of a concentrated layer of a fluidized bed reactor, by catalytic oxydehydrogenation reaction of a ≥4C monoolefin in a fluidized layer reactor in which oxygen and a specific catalyst are made present. <P>SOLUTION: The method for producing a conjugated diolefin includes bringing a ≥4C monoolefin into contact with a catalyst in which a metal oxide is carried on a carrier in a fluidized layer reactor in which the catalyst and oxygen are present inside, wherein the temperature of the concentrated layer of the fluidized bed reactor is controlled in the range of 320 to 400°C, and the temperature of a dilute layer is controlled in the range of -50 to +20°C with respect to the temperature of the concentrated layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
