Abstract
In one embodiment, a method of treating a gas stream comprises: controlling an amount of the NH3 entering a catalytic unit and converting NO2 and the NH3 to N2 in the catalytic unit, wherein greater than or equal to about 60 wt % of NOx initially in the gas stream is converted to N2. In one embodiment, a gas treatment system comprises: a plasma reactor disposed downstream of an engine; a cracking catalyst disposed downstream of the engine; and a catalytic unit capable of converting NO and HC to NH3, and capable of converting NH3 and NO2 to N2.
