Dual-Zone Catalyst for Ozone-Assisted Hydrocarbon Abatement at Low Temperatures

A dual-zone catalytic systems 10%Mn/Al2O3||10%Ag/Al2O3 has been developed for the low temperature light alkanes oxidation in presence of ozone. The upstream bed (10%Mn/Al2O3) is responsible for the ozone catalytic oxidation (OZCO) of light alkanes, while the downstream bed (10%Ag/Al2O3) provide effective carbon monoxide abatement and O-3-slip decomposition. The system demonstrates effective removal of hydrocarbons at 100 degrees C for a long time.
