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 Although it has been widely used in industrial production, the high-octane gasoline obtained from the alkylation of isobutane and 1-butene has many shortcomings, such as the search for solid acid catalyst - molecular sieve, sulfonic acid resin and solid super Strong acid has been widespread attention of scholars at home and abroad. The research on superacid mainly concentrates on SO 4 2- / oxide catalysts. These catalysts have high acid strength, good thermal stability and simple preparation. They are more effective in the alkylation of isobutane and 1-butene High reactivity, but there is coke, life expectancy
