Selective catalytic reduction of nitrogen oxides in the presence of iron-containing aluminosilicate zeolites |
摘要 |
There is disclosed a method of using iron-containing aluminosilicate zeolite having both framework iron and iron cations on the ion-exchange sites in a selective catalytic reduction reaction, typically in the presence of ammonia, to reduce or remove nitric oxides from exhaust emissions. |
