Description
| - Práce shrnuje dosavadní stav poznání o aktivitě metallo-zeolitů a Ag/aluminy v katalytickém odstranění kysličníků dusíku z exhalátů spalovacích procesů za podmínek chudých směsí. Přehled je sosutředěn na selektivní katalytickou redukci NOx uhlovodíky na molekulární dusík (HC-SCR-NOx) na Co-. Fe- a Ag-zeolitech a Ag/alumině, tzn. katalyzátorech vykazujících vysokou a stabilní deNOx aktivitu v exhalátech obsahujících velký přebytek vodní páry vyskytující se při spalování chudých směxí. Analýza struktury těchto katalyzátorů je popsána s použitím spektrálních, difrakčních, adsorpčních a redox technik. Je prezentovány možnosti korelace analyzovaných struktur katalyzátorů s jejich HC-SCR-NOx aktivitou. (cs)
- The paper reviews the state of the art of the activity of metallo-zeolites and Ag/alumina in catalytic abatement of nitric oxides from exhaust gases from lean-burn combustion processes. The review is centered on the selective catalytic reduction of NOx by hydrocarbons to molecular nitrogen (HC-SCR-NOx) over Co-, Fe- and Ag-zeolites, and Ag/alumina, i.e. those providing high and stable deNOx activity in streams containing a high excess of water vapor existing under lean-burn combustion conditions. Analysis of the structure of these catalysts is described by employing a combination of spectral, diffraction, adsorption and redox techniques. An attempt is made to correlate the analyzed structure with the HC-SCR-NOx activity.
