Catalytic DeNOx in biomass-fired plants

The objective of the project was to study new deNOx catalysts with improved alkali resistance in relation to flue gas from biomass-fired facilities. Alkali resistance of three types of catalysts is so promising that further research and industrial prototype testing should continue. The project studied three particular different catalyst types: 1. Metal oxide sulphated zirkonium catalysts. 2. Sepiolite-based metal oxide zirkonium catalysts 3. Nanoparticle catalysts. Patent right applications were submitted for two types, and joint work is still ongoing with Haldor Topsøe on prototype development.
