Embodiment 1
[0046] Compared with Comparative Example 1, in Example 1 of the present invention, the toothed weir type shock-reducing and equalizing plate of the present invention is set in the upper head of the hydrogenation reactor, using such as figure 1 The toothed weir type anti-flush equalizer plate shown is used in combination with the common ERI type bubble cap type gas-liquid distributor. The parameters of the toothed weir type flow-distributing disc are as follows: the distributing disc is a disc-shaped structure with a diameter of 120mm; the height of the outer edge is 30mm; The height is 30% of the hem height. The height of the space between the bottom edge of the flow equalizing plate and the upper edge of the descending pipe is 40 mm; the number of the equalizing plate and the descending pipe is the same, and the flow equalizing plate and the descending pipe are arranged in an up and down structure, and the center line of the flow equalizing plate is in line with the descendin...
Embodiment 2
[0048]The same as Example 1, the difference is that the conventional ERI gas-liquid distributor in the field in the original hydrogenation reactor is canceled, and only the toothed weir type anti-flushing equalizer provided in the present invention is retained, and the bed diameter is The temperature and temperature difference are shown in Table 1.
