Abstract

The deactivation of a silver-based hydrocarbon selective catalytic reduction catalyst by SOx and the subsequent regeneration under various operating conditions has been investigated. Using a sulfur trap based on a silica-supported catalyst it was found that, for a Ag/SiO2 + Ag/Al2O3 combination, the negative effect of SO2 on the n-octane-SCR reaction can be eliminated under normal operating conditions. The trap can be regenerated by hydrogen at low temperatures or at higher temperatures using a hydrocarbon reductant.
