Galejová, K. ; Obalová, L. ; Pacultová, K. ; Lacný, Z. ; Kovanda, F. ; Jirátová, Květa
Mixed oxide Co-Mn-Al catalysts were promotes by metals Pd, Pt, La, K and Ce. In simulated proces conditions (in the presence of O2, NO, NO2, H2O) catalytic activity, as well as thein regeneration was studied. The most active catalyst is that one with 3 wt. % K.

Catalytic Methods in Decrease of N2O Emissions: II. Catalysts Based on Hydrotalcites – Results of Investigation.
Pacultová, K. ; Obalová, L. ; Kovanda, F. ; Jirátová, Květa ; Lacný, Z. ; Valášková, M.
Activity of the two- and three component catalysts prepared by calcinations of Ni, Cu, Co, Mn, Mg, Al hydrotalcites in various molar ratios, partly modified with Pt, Pd, La, or K, was studied. Influence of O2, NOx, or H2O present in the reaction mixture on activity and stability of the most active catalyst was also investigated. Based on the laboratory results the size of a hypothetical industrial reactor was calculated.
