  • Fluidized-bed catalyst suitable for the production of halogenated aromatic nitriles, its preparation and application thereof
    Patent number: 10894247
    Abstract: A fluidized-bed catalyst suitable for the production of halogenated aromatic nitriles includes an active component and a support. The active component is a complex having the following composition expressed in atomic ratio: VPaCrbAcMdOx, wherein A represents at least one metal selected from the group consisting of alkali metals and alkaline earth metals; M represents at least one element selected from the group consisting of Ti, Zr, Hf, La, Ce, Nb, Mo, W, Co, Zn, Fe, Ni, B, Sb, Bi, As, Ga, Ge, Sn, and In; in the XRD spectrum of the catalyst, diffraction peaks are present at 2?=27.8±0.5° and 2?=13.8±0.5°, and the ratio of the height (I1) of the diffraction peak at 2?=27.8±0.5° to the height (I2) of the diffraction peak at 2?=13.8±0.5° is 3.5-6, i.e. I1:I2=3.5-6.
