CATALYST FOR THE REMOVAL OF NITROGEN OXIDES (NOX) FROM INDUSTRIAL OFF-GASES AT LOW TO MEDIUM TEMPERATURES
EnviCat™ NOx
Edition Date :
March 15, 2026
Selective Catalytic Reduction (SCR) is a robust and cost effective technology for reduction of nitrogen oxides (NOx) from industrial off-gases at low to medium temperatures. NOx consists primarily of nitric oxide (NO) and nitrogen dioxide (NO2).
The largest output of NOx emissions from non-automotive sources emanate from coal fired boilers, especially those in power generation. Petrochemical processes also produce large amounts of NOx, originating from utility boilers, cogeneration units, process heaters, steam methane reformers, ethylene cracking furnaces and fluid catalytic cracking (FCC) regeneration units. NOx contributes to the formation of smog, ground level ozone, acid rain, and other hazards.
EnviCat NOx facilitates NOx reduction reactions in the presence of oxygen. It uses ammonia (NH3) as a reducing agent to convert NOx pollutants into harmless nitrogen and water. The catalyst has been demonstrated to effectively lower NOx emissions from gas fired exhaust streams.
