Dechlorination of chlorobenzene on vanadium-based catalysts for low-temperature SCR

Abstract

Chlorobenzene (CB) inhibits SCR activity of V-based catalysts at low temperature, though the adsorption amount is small. NH3 adsorption increases due to the break in the C–Cl bond during CB oxidation. The dissociated Cl ions provide extra Brønsted acid sites, leading to the formation of inactive NH4Cl. Ce and Mn improve dechlorination, forming more NH4Cl on the catalyst surface.
