Catalytic oxidation of NO over Ru/γ-Al2O3 for industrial fertilizer production

We propose to study the active state of 0.5 and 5 wt% Ru on γ-Al2O3 at typical NO oxidation conditions for industrial fertilizer production. Hardly any literature reports exist on catalytic oxidation of NO at high concentrations and pressure, but our research proves that Ru on γ-alumina is a promising catalyst for NO oxidation with water, 4 bar pressure and high NO concentration. Compared to ambient condition performance, the ruthenium catalyst shows promising NO conversions at higher pressure and lower temperature. We therefore want to perform an in-situ investigation on how ruthenium in ambient and 4 bar of pressure. XAS-XRD in combination with mass spectrometry is an excellent combination for studying the local Ru environment in these catalysts at industrially relevant conditions.
