N₂O Decomposition & DeNOx Technology

BASF supplies catalysts and technologies to reduce emissions from stationary sources and industrial processes. Tailor-made solutions, catalyst services and long-term experience in emission reduction help our customers fulfill their sustainability goals.

BASF’s N₂O decomposition technology adsorbs N₂O (laughing gas) and almost eliminates N₂O emissions. The decomposition of 1 metric ton of N₂O has the same effect as of saving 298 metric tons of CO2. To break down N₂O into its harmless, natural components, (N2 and O2), BASF has developed a series of decomposition catalysts.

Moreover, BASF offers catalysts for the selective catalytic reduction of NOx (DeNOx) from stationary source gases. This process enables the elimination of pollutants without producing any residues which require disposal.

The catalysts can be used to eliminate and reduce harmful substances in a great varierty of applications, such as:

  • Nitric acid plants
  • Adipic acid plants
