The past and present research of the iron catalyst for ammonia synthesis carried out in the Institute of Chemical and Environment Engineering of Szczecin University of Technology has been described. The role of promoters, especially alkali metals, has been explained. The structure of the surface of active iron catalyst has been proposed. The behavior of iron catalyst during the reaction of nitriding...
The influence of the potassium concentration change on the surface area and active surface of an iron catalyst for ammonia synthesis was studied. The removal of potassium leads to the increase of the surface area, while potassium addition gives rise to the decrease of the surface area which is accompanied by the fourfold increase of the active area. The mechanism of the reduction of iron catalyst...
