Does the hydrogen sulfide content in the shifted gas have an impact on the catalyst in the shift converter?
Thread Content
The normal sulfur content in the shifted gas is over 1,000 PPM, but recent analyses show it to be around 400 PPM. Does this sulfur content have any impact on the catalysts in the shift reactor? Is it better if this level is high or low?
For catalysts that have been fully vulcanized and are in normal use, the sulfur content does not affect their operation.
The sulfur content should also not be too low, to prevent the occurrence of \"back-sulfidation\" which can affect catalyst activity.
It depends on what type of catalysts you have; generally, they are sulfur-resistant catalysts. Catalysts require a minimum level of hydrogen sulfide, and in our case, this level must not be lower than 300 PPM. Too low will lead to reverse sulfidation
