Process for removal of hydrocarbons carbon manoxide, and oxides of nitrogen from oxygen-containing waste gas using molecular sieve- palladium- platinum catalyst on a substrate

摘要

A process of using a catalyst system for the oxidation of hydrocarbons, carbon monoxide, and the reduction of nitrogen oxides is provided. The unique synergy of the catalyst system, a combination of molecular sieves and noble metals, provides a system that partially or entirely replaces the need for rhodium as a catalyst in three way catalyst systems.
