(582ce) Novel Approach of NOx Removal from Exhaust Gas

Abstract: As a result of harmful environmental and health effects brought by NO_x emission, it is necessary to minimize NO_x pollutant released into the atmosphere. Conventional SCR systems involve anhydrous or aqueous ammonia (NH₃) or urea (CO(NH₂)₂) as a reducing reagent to reduce NO_x to harmless N₂ and H₂O at high temperature 300-400 °C.¹ It is still a big challenge to develop novel low-temperature catalyst (LTC) for SCR of NO_x.^2,3This work focused on investigation on novel supported ionic liquid phase (SILP) catalysts and application of hydrocarbon (C_xH_y) or CO presented in exhaust gas from marine engine as reducing agent for SCR instead of using urea or ammonia.
