摘要
制备了不同酸度的催化剂ＨＭ０３０１，ＨＭ１３０１，ＨＭ２３０１，ＨＭ３３０１，ＨＭ４３０１，探讨了催化剂载体酸性质对正戊烷异构化的影响。考察了离子交换对催化剂酸性质的影响及钠离子交换度对催化剂性能的影响。实验结果表明，ＮｉＭｏＨＭ双非贵金属催化剂的异构化活性随着丝光沸石残钠量的降低而提高，铵交换可以改变丝光沸石分子筛的表面酸性质使酸度达到最佳分布，从而有利于提高异构化的活性；残钠量接近１．３５％时，催化剂性能最好：正戊烷转化率６７．２％，异戊烷收率６２．２％，异戊烷选择性９２．５％，液体收率９６．１％。
Catalists with different acidity are prepared: HM0301,HM1301,HM2301,HM3301,HM4301. Effects of addition competition absorbent of catalyst on catalytic properties were investigated.Expermental results show that the isomerization activity and seclectivity of Ni HM catalyst are increased compared with non addition competition absorbent catalyst. Results from runs over HM3302 catalyst show that, at the same reaction condition, n pentane coversion and iso pentane yield are increased by 5.6%～10.3% and 5.7%～9.4% respectively.
