Catalyst Fouling
Deposits that cover surfaces or block pores and flow paths.
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
Deposits that cover surfaces or block pores and flow paths.
Core catalyst ideas
Fouling can reduce access to active sites without chemically destroying platinum.
Deposits can also increase pressure drop in structured or packed catalyst systems.
Cleaning or regeneration must follow application-specific procedures.
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.
