Published in 2025 at "AIChE Journal"

DOI: 10.1002/aic.70083

Abstract: In industrial zeolite catalysis, high‐temperature (>650°C) air combustion is commonly used to restore the activity of catalysts deactivated by coke deposition. Herein, we propose a low‐temperature (440–500°C) air regeneration strategy that harnesses spatially restructured coke… read more here.
