The nature of the potassium compound acting as a promoter in iron-alumina catalysts for ammonia synthesis [PDF]
, 1975 The chemical form of the potassium promoter on an iron-alumina catalyst during ammonia synthesis has been studied by two methods, viz, (i) the measurement of the equilibrium constant of the process KNH2 + H2 KH + NH3, and (ii) chemical analysis of the ...
