A method of preparing a hydrothermally stable zeolite catalyst. |
摘要 |
<p>In a method for preparing a hydrothermally stable zeolite catalyst, a zeolite having a Constraint Index of 1 to 12, a silica to alumina mole ratio of 12 to 100 and having incorporated therein Cu<+><+> cation is contacted with a reducing agent comprising a mixture of CO and NH3 having a molar ratio of CO:NH3 ranging from 50:1 to 1:1, at a temperature of 400 to 550 DEG C (750 to 1022 DEG F) and a pressure of 10<-><1> to 10<4> kPa so as to reduce at least some of said Cu<+><+> cations to Cu<+> cations.</p> |
