The effect of tungsten on the activity of CeOx/TiO2 catalysts for the SCR of NO by NH3 was studied with catalysts of similar composition prepared via different impregnation routes from precursors used in industry. Reaction rates were related to struc

Hybrid catalysts for the selective catalytic reduction of NO by NH3, which have been introduced as physical mixtures between an oxidation catalyst and an SCR catalyst, have been prepared by precipitation of the former onto the latter. Mn oxide, CeO2,

We analyzed clouds macrophysics and their radiative effects according to COSMO mesoscale atmospheric model and measurements at Lindenberg Observatory (Germany). Different cloud parameters simulated by the model and derived from measurements of ground

The selective catalytic reduction (SCR) of NO by NH3 was investigated over physical mixtures of an oxidation catalyst with an SCR catalyst (“hybrid catalyst”) in which the components were arranged in variable distance to each other: pressed in mi
In-situ profiles of all four net radiation components were obtained at Ny Ålesund/Svalbard (78.9° N, 11.9° E) in the time frame May 04–21, 2015. Measurements could be performed using adapted high quality instrumentation classified as secondary s

The SCR of NO by NH 3 was studied with hybrid catalysts, in which an oxidation component (Mn-Cu or Ce-Zr mixed oxides) and SCR catalysts of different activities in fast SCR (Fe-ZSM-5 of different Fe content and H-ZSM-5) are combined in physical mixtu
