NOx Reduction Catalysts for Vehicle Emission Control

This project developed and evaluated a catalyst system for oxides of nitrogen control to achieve target reduction levels established for the Inter-Industry Emission Control (IIEC) Program, with concurrent control of the hydrocarbons and carbon monoxide. The major effort described is the evaluation of catalysts and the development of a suitable exhaust gas-temperature environment. The objective was met, with the exception of long-term durability, by using a pelleted, nonnoble metal catalyst and a special container design.
