Fighting hydrocarbon poisoning with alkali metal poisoning on Cu-SSZ-13 catalyst for NH3-SCR

Key Points

• Enhanced catalytic activity was achieved for ammonia selective catalytic reduction (NH3-SCR) processes with alkali metal intervention.
• Cu-SSZ-13 catalysts exhibited improved ammonia selectivity, countering the effects of hydrocarbon poisoning.
• Analysis utilized alkali metal poisoning interventions on Cu-SSZ-13, focusing on restoring catalytic performance.
• Findings may enable better performance of SCR catalysts in real-world applications; future work needed for field implementation.
