METHOD AND APPARATUS FOR REDUCING NOX WITH FIRST AND SECOND CATALYSTS
摘要
<p>A method and apparatus for catalytically processing a gas stream passing therethrough to reduce the presence of NOx therein, wherein the apparatus includes a first catalyst composed of a silver containing alumina that is adapted for catalytically processing the gas stream at a first temperature range, and a second catalyst composed of a copper containing zeolite located downstream from the first catalyst, wherein the second catalyst is adapted for catalytically processing the gas stream at a lower second temperature range relative to the first temperature range.</p>
