Do you know what is the reason for the deactivation of the catalyst? The editor of quality Mesoporous Y Zeolite Catalyst will take you to a brief understanding.
1. Permanent inactivation
The active component of the catalyst is deactivated by the action of some foreign components, often permanently. Most of these foreign components are chemically reacted or ion exchanged with the active components of the catalyst, resulting in changes in the active components. For example, acidic catalysts are neutralized by alkalis, and noble metal catalysts are poisoned by sulfides or nitrides. Deactivation of catalyst poisoning often manifests itself as a rapid decrease in activity. Loss of active components due to wear or sublimation during use also leads to permanent inactivation, which is often difficult to restore simply.
2. The active components are covered and gradually inactivated, which is non-permanent inactivation. For example, the carbon deposition generated in the reaction process covers the active components or blocks the pores of the catalyst, so that the reactants cannot be contacted with the active components. These coverings can be removed by certain methods, such as being deactivated by carbon deposition, and can be revived by burning charcoal for regeneration.
The above is the introduction of quality Mesoporous Y Zeolite Catalyst editor: introduction to the reasons for catalyst deactivation.
