What is the major cause of the catalyst deactivation ?
The primary mechanism of deactivation is thermal desulfonation

 

 

 

 

Is this deactivation reversible ?
Unfortunately the loss of sulfonic group is permanent. It results in a loss of acid site concentration (total weight exchange capacity).

 

 

What is the typical catalyst lifetime ?
It varies from 3 months to almost 2 years.
