提出了一种高温氨选择性催化氧化法脱除克劳斯工艺中氨杂质的方法。Cu取代的六铝酸盐催化剂在约520 °C下实现了最高的N2产率，并且反应遵循i-SCR机理。
A method for selective catalytic oxidation of ammonia at high temperature was proposed to remove the ammonia impurity in the Claus process. Cu substituted hexaaluminate catalysts achieved the highest N2 yield at around 520 °C and the reaction followed the i-SCR mechanism.
