焙烧温度和还原温度对Pt/HM催化剂性能的影响

Effects of Calcination Temperature and Reduction Temperature on the Catalytic Behavior of Pt/HM

以Ｐｔ为催化剂的金属活性组分，丝光沸石为载体，制备了Ｐｔ／ＨＭ催化剂，用于正戊烷异构化反应．考察了焙烧温度及还原温度对Ｐｔ／ＨＭ催化剂的催化性能的影响．实验结果表明，焙烧温度和还原温度均在３５０℃时，Ｐｔ／ＨＭ催化剂具有优良的正戊烷异构化活性，正戊烷转化率为７１．２％，异戊烷收率为６８．１％，异戊烷选择性为９５．７％，液收率为９７．０％．

For isomerization of n\|pentane over mordenite, pt/HM catalyst was prepared with Platinum as the active component. The effects of reduction temperature and calcination temperature on the catalytic behavior of Pt/HM were investigated. The result show that Pt/HM reduced and calcinated at 350 is a better catalyst for n\|pentane isomerization, n\|pentane conversion rate is 71.2%; isopentane yield is 68.1%; isopentane selectivity is 95.6%; liquid product yield is 97.0%.
