Cs doped cobalt based deN2O catalyst-Pilot plant results

Original language description

The Cs-doped Co-Mn-Al mixed oxide deN2O catalyst was prepared by calcination of Co-Mn-Al layered double hydroxide, subsequent impregnation with Cs2CO3 and shaping into tablets 5x5 mm. Tablets were tested for N2O decomposition in pilot scale reactor connected at the bypassed tail gas from the nitric production plant downstream of the SCR NOx/NH3 catalyst with the aim to perform kinetic measurements. A special attention was paid to study the changes in the catalytic performance, which was monitored using both the long-Term catalytic test and the comparison of physical-chemical properties of the fresh and used catalyst. The changes in catalyst reducibility, caused by the time-on-stream operation of the catalyst for 142 days in the pilot reactor, did not negatively affect the catalytic performance. High and stabile performance in the N2O removal was reached-Average value of N2O conversion 75 ± 7 % at 450 °C was kept (WHSV = 8,1 kggas kgcat-1 h-1). The presented data can be used to assess the necessary amount of a real catalyst for N2O emission lowering in different plants operating at specific conditions.
