Various catalysts are employed for the removal of SOx, depending on the specific application and desired outcome. Some commonly used catalysts include:
1. Vanadium Pentoxide (V2O5): Often used in SCR processes to reduce SOx to elemental sulfur or sulfuric acid.
2. Titanium Dioxide (TiO2): Frequently used as a support material in SCR catalysts.
3. Zeolites: These microporous materials can be used in certain catalytic processes to adsorb and convert SOx.
4. Activated Carbon: Used in dry scrubbing processes to adsorb SOx from gas streams.
