Embodiment 1
[0029] Such as figure 1 The device for producing aniline by hydrogenation of nitrobenzene is shown. The average particle size of the catalyst is 360 mu m, the largest angle α in the triangular longitudinal section of the left baffle and the right baffle is 135°. The sides of the prism where the longer side of the triangular longitudinal section of the left baffle and the right baffle of the composite member are located are parallel to each other and placed vertically. The sides of the left baffle and the right baffle of the composite component have holes and (or) slits respectively, and the ratio of the total area of the holes and (or) slits to the area of the blades is 15%. Four composite components are set in the fluidized bed reactor, and the composite components are staggered and evenly distributed in the reactor, and the acute angle / right angle between two adjacent composite components in the vertical direction is 90°, and the vertical direction The vertical dista...
