Aluminosilicate or silicoaluminophosphate as a catalyst for treating exhaust gas Molecular sieves / manganese octahedral molecular sieves

摘要

Catalysts and articles useful for selective catalytic reduction (SCR) and other exhaust gas treatments are disclosed. The catalysts comprise an octahedral molecular sieve (OMS) comprising manganese oxide and an aluminosilicate and/or silicoaluminophosphate large-pore or medium-pore molecular sieve.
