摘要：
The kinetics of ammonia decomposition over an iron catalyst poisoned with sulphur has been studied. The relative activity of this catalyst decreases with increasing concentration of sulphur and increases with increasing temperature. As the simple site-blocking mechanism of poisoning cannot explain this behaviour, the formation of stable sulphur compounds and the evolution of the catalysts' active surface with the temperature was proposed to account for the results.
