What are the causes of deactivation of hydrotreating catalysts?
Following are the causes of deactivation of hydrotreating catalysts;
1. Deactivation due to coke formation or carbon lay down. To control this deactivation please view the Avoid Coke Formation in hydrotreating catalysts
2. Catalyst sintering, at abnormal high temperature operation.
3. Metal poisoning due to metals present in the feed stock. To control this view Solving Fouling Problems of Hydrotreating Reactor and
