Ammonia Synthesis Plant Ammonia Synthesis Catalyst
Ammonia synthesis catalyst is used to accelerate the chemical reaction to produce ammonia, a crucial compound used in various industries such as fertilizer, chemical manufacturing and metal processing as well as electronic industry which gets nitrogen from NH3.
Ammonia synthesis catalyst is an iron-based catalyst containing a number of selected promoters. These promoters can reduce the activation energy of the reaction, making it easier for N2 and H2 to react to generate NH3 and speed up the reaction speed.
The reaction is summarized below:
N₂+3H₂ ⇌ 2NH₃
The ammonia synthesis catalyst is supplied in its oxidic form or as pre-reduced form.
