Preparation and Activation of the Technical Ammonia Synthesis Catalyst
Abstract
“The active catalyst for the ammonia synthesis is alpha iron with small amounts of oxidic additives.... The quality of the final catalyst is crucially influenced by the activation process which is the reduction of magnetite to metallic iron. It is important to minimise the concentration of the reaction product water which is a catalyst poison.”(1)
“... shows how the pore size distribution of the KM 1 catalyst varies with reduction temperature.... The peak of small pores represents a pore system formed by the reduction of magnetite, while the system of larger pores is formed by the reduction of wustite... the surface area of the catalyst reduced at higher temperature is smaller than of that reduced at a lower temperature.”(2)
