| description | The invention discloses a catalyst fast dispersion method. The method comprises determining a grain flow pattern in a reactor, determining axial height and radial depth of an outlet of a catalyst injection tube based on the grain flow pattern, and carrying out fast and uniform dispersion on the catalyst in the reactor under the condition of smooth catalyst injection. The axial height of the outlet of the catalyst injection tube is in a range of 0-1/4L of the lower part of a particle main cycle zone, the radial depth of the outlet is in a range of 1/4-3/4D in the main cycle zone, L represents the particle main cycle zone length and D represents the reactor diameter. The catalyst fast dispersion method realizes fast and uniform dispersion of the catalyst in a reactor and prevents polymer adhesion to wall and caking caused by nonuniform catalyst dispersion or catalyst adhesion to wall. |
