Full low variation, one change, overtemperature

During the operation of the full low-temperature shift process, bed overheating often occurs. How should this be adjusted?
Is it feasible to control the conversion rate using steam volume?
First, check for issues such as insufficient catalyst loading or bed layer misalignment； Furthermore, adjust the air supply to each converter as appropriate, and finally use steam or inert gas, since there are requirements regarding the overall conversion rate
Most cases of excessive temperature during transformation are caused by a low flow rate of gas during gas introduction, and measures should be taken in this regard.
It’s about controlling the air velocity during gas guidance, right! Thank you!
For specific adjustment, it’s about using the gas flow rate and vent pressure to prevent overheating issues! Some processes incorporate nitrogen as a regulator at low load conditions.
What is the oxygen content in the water gas that comes in?
Check whether the gas-water-air ratio and CO content in the gasified gas fluctuate, as well as whether the converter load is too low
