Description
2NO+4NH3+2O2→3N2+6H2O
2NO2+4NH3+O2→3N2+6H2O
が挙げられる。
8NO2+6NH3→7N2O+9H2O
4NO2+4NH3+O2→4N2O+6H2O
2NH3+2O2→N2O+3H2O
などの経路を介してN2Oが形成可能になる。したがって、NOx転換を改善し、N2O生成を低減する改善されたSCR触媒が依然として必要とされている。本発明は、とりわけこれらの必要を満たすものである。
CHA骨格を有し、約25のSARを有するNH4 +型ゼオライトの試料を室温で酢酸銅溶液に添加して、銅交換ゼオライトを生成した。銅交換ゼオライトを乾燥、600℃でか焼し、ゼオライトの重量に対して約3.3重量%の銅を有するゼオライトを得た。
CHA骨格を有し、約13のSARを有するNH4 +型ゼオライトの試料を室温で酢酸銅溶液に添加して、銅交換ゼオライトを生成した。銅交換ゼオライトを乾燥、約600℃でか焼し、ゼオライトの重量に対して約3.5重量%の銅を有するゼオライトを得た。
