Anticipating more stringent emission limits, Rhone-Poulene has developed a new generation of selective catalytic reduction (SCR) catalyst named DN115 improving performances especially at low temperature. Data on the commercially available vanadium oxide-based catalyst DN115 are presented. Effects of operating temperature, pressure, gas composition and space velocity are also investigated. A kinetic model has been established. The DN115 catalyst is also effective for the control of a variety of other NOx emissions, such as industrial boilers like chemical waste incineration or other chemical processes.
