Kinetics and isotope effect of ammonia synthesis over a singly-promoted iron catalyst

The kinetics and deuterium isotope effect of the ammonia synthesis reaction over a singly-promoted iron catalyst have been studied at 305 °C under reduced pressures. The kinetic data as well as the isotope effect are essentially the same as those on the unpromoted iron previously reported. This result confirms that the potash promoter is more important in the mechanism of ammonia synthesis.
