Ammonia synthesis

Abstract From the Canadian patent

A process for producing ammonia by reaction of a hydrogen and nitrogen-containing synthesis gas in the presence of a solid particulate catalyst for the reaction includes conducting the reaction at pressures significantly lower than that of conventional ammonia synthesis e.g. at about, 30 to 70 atmospheres, in a fluidized bed Or the catalyst. The synthesis gas 18 used to fluidize the catalyst and the resultant fluidized bed 18 preferably maintained under substantlally isothermal conditions, e.g. by flowing a coolant liquid in indirect heat exchange relationship with the fluidized bed. Suitable catalysts for the process include activated iron catalysts which may be Or very fine particle size.
