Catalyst Poisoning
How strongly adsorbed contaminants can block or alter active sites.
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
How strongly adsorbed contaminants can block or alter active sites.
Core catalyst ideas
A poison reduces activity by interacting strongly with catalytic sites or changing surface chemistry.
Sensitivity depends on reaction, platinum state and contaminant.
Feed purification and material compatibility can be important prevention strategies.
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.
