[EN] The SCR technology has become in the last years one of the most investigated issues referring to removal of NOx from diesel exhaust gases. Although V2O5/WO3/TiO2 catalysts have been proved to be efficient in stationary SCR plants, a current issue of research is the substitution of theses catalysts arising from their limited thermal resistance and vanadium toxicity. Hence, at the Institute of Technical Chemistry and Polymer Chemistry of Karlsruhe Institute of Technology a lot of effort is aimed on Fe/HBEA catalyst. The 0.25Fe/HBEA zeolite (0.25 wt.% Fe on HBEA zeolite) has been recently reported to have superior activity and hydrothermal stability as referred to V2O5/WO3/TiO2.
