What can be done to address the large radial temperature difference in the hydrogenation reactor bed?
Thread Content
The radial temperature difference in the bed of the hydrogenation reactor is large, exceeding 15 degrees. What solutions are available?
Reasons for the large radial temperature difference in the hydrogenation reactor bed: 1. Poor quality of catalyst packing. 2. The inlet flow rate of the reactor is too low; firstly, the hydrogen-to-oil ratio is too small, and secondly, the space velocity is too low, resulting in flow deviation within the reactor. 3. Partial coking occurs in the catalyst bed, affecting gas flow distribution. 4. Clogging of the distribution tray blister. Solution: 1. Reload the catalyst. 2. Increase the hydrogen-to-oil ratio or space velocity. 3. The catalyst is regenerated and then reloaded. 4. Clean the distribution tray.
It is closely related to the arrangement of the internal components of the reactor; the performance of these internal components varies among different patent holders. Additionally, the quality of the catalyst loading is also an important factor.
