The present invention relates to a catalyst for butadiene production by oxidative dehydrogenation of butene used in a fluidized bed reactor, and a production method and use thereof, and the method comprises reacting a metal precursor with a basic substance to contain an insoluble compound. Obtain slurry, filter and wash, add adhesive and deionized water, stir, adjust so that solid content of slurry is 10% to 50%, and spray dry granulation Then, the temperature of the charging port is set to 200 ° C. to 400 ° C., the temperature of the discharge port is set to 100 ° C. to 160 ° C., catalyst microspheres are obtained, and further dried at 80 ° C. to 200 ° C. for 1 to 24 hours. Calcination at 4 ° C for 24 to 24 hours to obtain a catalyst containing a metal such as Fe, Mg, Zn, Bi, Mo, Mn, Ni, Co, Ba, Ca and having a general formula of FeX a Y b Z c O d Including. The catalyst produced in the present invention has high fluidity of granules, suitable particle size distribution, high mechanical strength and catalytic activity, and is suitable for butadiene production reaction by butene oxidative dehydrogenation in an industrial fluidized bed. . The catalyst is used for the production of butadiene by oxidative dehydrogenation of butene, with a butadiene yield of 76% to 86% and a butadiene selectivity of 94% to 97%. [Selection] Figure 2 |
