Catalyst Poisons

Subject: Chemistry

Book: General Chemistry

Catalyst poisons are substances that deactivate catalysts by binding strongly to active sites, preventing the intended reactants from adsorbing or reacting. Examples include sulfur compounds poisoning metal catalysts used in hydrogenation. Preventing or removing poisons is crucial for prolonging catalyst life and ensuring consistent performance in industrial processes. Designing poison-resistant catalysts is an active area of research.
