Argonne develops new NOx catalyst; up to 95-100% NOx removal

A new cerium-oxide catalyst developed by researchers at the Department of Energy's Argonne National Laboratory is showing promise for the efficient reduction of NOx emissions in diesel engine exhaust. The technology has been under development for a number of years and has a patent pending. A number of companies have expressed interest in licensing the technology and working with Argonne researchers to scale it up and bring it to market. Argonne researcher Christopher Marshall, one of the technology's developers, believes there could be a commercially available product within two to three years.

"Our new cerium-oxide additive is the breakthrough that makes it work. When it's combined with Cu-ZSM-5, the resulting catalyst works at normal exhaust temperatures and is actually more effective with water vapor than without it. With a lean fuel-air mixture, it removes as much as 95-100 percent of NOx emissions." - Christopher Marshall

Marshall says the Argonne catalyst has been tested and performed well with a number of diesel and diesel-type fuels, including standard diesel, synthetic diesel, biodiesel and JP-8. Having performed well in these tests, the next step is to subject the catalyst to engine testing, which will soon take place soon at Argonne's Diesel Engine Test Facility. Marshall expects these tests will show that in addition to its other advantages, the Argonne catalyst has a greater life expectancy than other catalysts currently on the market.
