A METHOD FOR LOW-TEMPERATURE REDUCTION OF NITROUS OXIDE USING A REDUCTANT OVER PLATINUM GROUP BI-METALLIC CATALYSTS CONTAINING COPPER AS A PRIMARY COMPONENT

摘要

The present invention has an excellent effect on effectively removing nitrous oxide in exhaust gas discharged from the rear side of a gas expander including a nitric acid production plant and an adipic acid production plant in a low temperature and high space speed, using hydrogen as a reducing agent under the presence of platinum group (containing gold and silver) bi-metallic catalysts which contains copper which is a low price metal as a primary component.
