PKR-2 catalyst for N2O abatement in HNO3 plants is shaped by an extrusion process, from a mixture of catalyst powder and plasticizing additives. The catalyst mass composition, allowing for its trouble-free shaping on an industrial extruder and producing catalyst extrudates with the best mechanical parameters, was opimized using capillary rheometry.
