Untersuchungen über die Kinetik und den Mechanismus der Bindung von Schwefeldioxid und Stickoxiden durch gasförmiges Ammoniak

Studies on Kinetics and Mechanism of the Reaction of Sulphur Dioxide and Nitrogen Oxides with Gaseous Ammonia It was found that depending on the partial pressure of SO₂, H₂O, and NH₃ different solid products were formed. Formation of the product containing the smallest amount of the substrate of the lowest partial pressure is favoured. The measured stability limits of the solid products confirmed the former thermodynamic calculations. The conditions for effective binding of NO_x with ammonia were established.
