Abstract
In response to the threats of global warming and climate change, the development of highly energy-efficient
lean methane oxidation processes has become crucial. One promising technology is ozone-induced lean methane oxidation
(O3-LMO), which utilizes ozone as an oxidant and a transition metal-loaded zeolite as a catalyst. Our previous study
demonstrated that the O3-LMO system, employing a cobalt-exchanged BEA (Co-BEA) catalyst, effectively abates lean
methane (500 ppm) at low temperatures below 200°C under dry conditions. In this study, we investigated the effect of
water vapors on the performance of Co-BEA-based O3-LMO system. The results indicated that CH4 conversion, CO2
selectivity, and O3 utilization efficiency of the system were not significantly affected by water vapors. Additionally, any
temporary suppression of activity could be easily reversed through simple vacuum drying of the catalyst. The system
maintained robust activity for over 18 hours during prolonged testing under wet conditions.
