摘要：以ＡｌＣｌ３和ＣＣｌ４为氯化剂，制备了Ｐｔ－Ｃｌ／Ａｌ２Ｏ３型Ｃ５／Ｃ６烷烃低温异构化催化剂，考察了补氯条件对催化剂异构化活性和选择性的影响，结果表明，以正己烷为原料，在氢压２．０ＭＰａ，进料质量空速１．０ｈ－１，反应温度１４０℃，氢油摩尔比１～２条件下，２，２－二甲基丁烷选择性３０％；ｎ－Ｃ６转化率９０％，经微反装置３００ｈ运转，催化剂活性未见下降。
A Pt Cl/Al 2O 3 catalyst for C 5/C 6 alkanes isomerization at low temperature was prepared using AlCl 3 and CCl 4 as chlorinating agent , and the effect of adding chlorine on the isomerizing acti vity and selectivity of the catalyst was investigated. Test results showed that selectivity and conversion of the catalyst with n hexane as feedstock were up to 29～30% and 89～90% respectively at a temperature of 140 ℃, hydrogen pressure of 2.0 Mpa, WHSV of 1.0 h -1 and H 2/oil ratio of 1￣2 mol. The activity of the catalyst remained after 300 h operation in a micro reactor, which reached the level of similar foreign catalyst.
