The heart of the nitric acid plant is the catalytic reactor where the mixture of ammonia and air reacts to form nitrogen monoxide, on a Pt/Rh catalyst. The catalyst comprises several layers of fine PlatinumRhodium (95%Pt and 5%Rh) mesh and the gases flow through this. Pt/Rh 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O ∆H = 903 kJ 890°C, 34 atm The catalyst gauzes are initially heated using a ...
