Abstract

Methods and systems for selective catalytic reduction of NOx with an activated carbon supported metal catalyst at an operating temperature of between about between about 500 °C and about 750 °C. An exhaust stream including NOx is introduced to a catalytic reactor having the activated carbon supported metal catalyst for NOx reduction of at least 90%. A second catalyst reactor can be provided downstream to remove or convert nitrous oxide as desired.
