The catalyst EnviCat N2O-S removes nitrous oxide (N2O) from the off-gas of nitric acid (HNO3) plants. Nitrous oxide – also known as happy gas or laughing gas – is around 300 times more harmful to the climate than CO2.
EnviCat N2O-S is a so-called “secondary abatement catalyst”: it is installed in the ammonia oxidation reactor directly underneath the primary precious metal gauze pack in a reactor basket.

ベネフィット
- Converts up to 95% of N2O into harmless oxygen and nitrogen
- The catalyst can also slightly increase nitric acid yield by improving the efficiency of the ammonia oxidation process
- Convenient “drop-in” solution: catalyst is easy to install with little or no engineering modifications
- Catalyst shapes optimized for low-pressure drop
- High mechanical strength: robust in commercial operation
