Frequently Asked Questions
Hydration of Light Olefins - Isopropyl Alcohol, s-butyl alcohol
• 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 6 months to almost 2 years. This is very dependent on the operating
temperature and the purity of the olefin feeds.
