| 摘 要： | 由异丁烷和1-丁烯烷基化合成高辛烷值汽油虽已被广泛用于工业生产,但由于液体酸催化剂存在许多缺点,寻找固体酸催化剂——分子筛、磺酸树脂及固体超强酸已受到国内外学者的广泛重视。对超强酸的研究多集中在SO_4~(2-)/氧化物催化剂上,此类催化剂的酸强度高、热稳定性好、制备简单,对异丁烷、1-丁烯烷基化具有较高的反应活性,但存在着积炭、寿命

| Abstract: | The alkylation of isobutane with 1-butene over Pt-SO42-/ZrO2 catalysts prepared with different methods is studied. The results show that Pt-SO42-/ZrO2 catalysts have a high reaction activity and selectivity for alkylation, and the reaction conditions are the same as for SO42-/ZrO2 catalyst. The addition and the adding methods of Pt did not affect the catalytic property, the crystal forms and stucture, and strength of the superacids according to the results of FTIR, XRD, XPS and acid strength measurement. When the alkylation reaction of isobutane with 1-butene takes place in hydrogen, the coke yield over the catalysts added with Pt is decreased and the life of the catalysts is extended. |
