What Are the Challenges Associated with Sulfation?
While sulfation offers many benefits, it also presents several challenges:
- Deactivation: Sulfated catalysts can suffer from deactivation due to the leaching of sulfate groups or the formation of carbon deposits. - Stability: Maintaining the stability of the sulfate groups at high temperatures can be difficult, affecting the long-term performance of the catalyst. - Cost: The sulfation process can add to the overall cost of catalyst preparation, especially if high-purity reagents are required.
