Clingy Copper Ions Contribute to Catalyst Slowdown
Date Time Clingy Copper Ions Contribute to Catalyst Slowdown Heavy-duty diesel trucks on the road today are equipped with aftertreatment systems that include selective catalytic reduction (SCR) technology using urea solution as a reducing agent to curtail harmful nitrogen oxide (NOx) emissions from engine exhaust before they reach the tailpipe. SCRs rely on a catalyst to help chemically convert NOx gases into nitrogen, water, and small amounts of carbon dioxide. Like anything else subject to the laws of nature, catalysts-materials that help a desired reaction efficiently take place-tend to sl...
