Abstract

PURPOSE: To reduce efficiently NO in the exhaust gas without causing the secondary environmental pollution, by reducing the concentration of ammonia with the addition of hydrocarbons in the presence of oxygen after ammonia has been added at high temperature to the gas containing NO in the presence of oxygen.
