Abstract

An exhaust gas treatment process, apparatus, and system for reducing the concentration of NOx, CO and hydrocarbons in a gas stream, such as an exhaust stream (), via selective catalytic reduction with ammonia is provided. The process, apparatus and system include a catalytic bed () having a reducing only catalyst portion () and a downstream reducing-plus-oxidizing portion (). Each portion () includes an amount of tungsten. The reducing-plus-oxidizing catalyst portion () advantageously includes a greater amount of tungsten than the reducing catalyst portion () to markedly limit ammonia salt formation.
