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％．
A Pt / HM catalyst was prepared by using Pt as catalyst and mordenite as support. The catalyst was used for the isomerization of n-pentane. The effect of calcination temperature and reduction temperature on the catalytic performance of Pt / HM catalyst was investigated. The experimental results show that the Pt / HM catalyst has excellent n-pentane isomerization activity at the calcination temperature and reduction temperature of 350 ℃, the n-pentane conversion is 71.2% and the isopentane yield is 68.1 %, Isopentane selectivity of 95.7%, liquid yield of 97.0%.
