Title: A CATALYST FOR TREATING AN EXHAUST GAS, AN EXHAUST SYSTEM AND A METHOD
Abstract:
A catalyst for treating an exhaust gas comprising S02, NOxand elemental mercury in the presence of a nitrogenous reductant comprises a composition containing oxides of: (i) Molybdenum (Mo) and optionally Tungsten (W); and (ii) Vanadium (V); and (iii) Titanium (Ti); and (iv) Phosphorus (P), wherein, with respect to the total metal atoms in the composition, the composition comprises: (i) Mo in an amount of less than 2 at.%, and optionally up to 9 at.% W; (ii) from 2.5 to 12 at.% V; (iii) from 85 to 96 at.% Ti, and wherein the composition comprises (iv) P in an atomic ratio to the sum of atoms of Mo, W and V of from 1:2 to 3:2. The values expressed must total 100%.
