Catalytic reduction of nitrogen oxides in automobile exhaust

Abstract

The catalytic reduction of oxides of nitrogen from leaded automobile exhaust has been demonstrated to be technically feasible. These studies made with copper-containing catalysts are based upon the reducing nature of exhaust caused by the carbon monoxide present. The reaction involves 2 CO + 2 NO → + N2 + CO2 + 178.5 Kcal. © 1964 Air & Waste Management Association.
