Selective catalytic reduction of nitric oxide with ammonia on Mn-promoted carbonized used silica-alumina sorbents

Deactivated (waste) silica–alumina sorbents were carbonized and used as supports. The introduction of manganese led to active and selective SCR catalysts at low temperatures. Two methods of Mn promoting were compared: wet impregnation and adsorption. They influenced the distribution of Mn and N2O pr...

Description
Summary:Deactivated (waste) silica–alumina sorbents were carbonized and used as supports. The introduction of manganese led to active and selective SCR catalysts at low temperatures. Two methods of Mn promoting were compared: wet impregnation and adsorption. They influenced the distribution of Mn and N2O production. The catalysts behaved similarly to Mn‐promoted active carbon.
