Oct 9, 2018 · This is where the DEF and catalyst come in. The DEF is added to the exhaust gas and then passed through the catalytic chamber. The catalyst itself can be composed of a variety of materials such a metals, metal oxides, perovskites and zeolites. The urea (CO (NH2)2) from the fluid reacts with the NO by: 4NO + 2CO (NH2)2 + O2 → 4N2 + 4H2O + 2CO2.
