Platinum Catalyst Deactivation
Why active catalyst can lose performance during service.
Industrial note: catalyst performance depends on the specific chemistry, reactor, feed and approved process conditions. This site explains system concepts rather than operating recipes.
What this topic covers
Why active catalyst can lose performance during service.
Core catalyst ideas
Deactivation can result from poisoning, fouling, sintering, structural change or physical loss.
Different mechanisms require different responses and are not interchangeable.
Trend data and post-service characterization help identify likely causes.
System tradeoffs
Monitoring should separate catalyst aging from changes in feed, reactor condition or measurement systems.
Performance evidence
Regeneration can restore some reversible losses but cannot reverse every form of damage.
Lifecycle perspective
Spent catalyst can retain substantial material value even when process performance is no longer acceptable.
