This work reports a new technical approach for the production of aviation gasoline through the catalytic dimerization of iso-butene on sodium exchanged Amberlyst-15 resins (20–40 mesh) in the absence of selectivity-enhancing components at T = 50 °C, P = 2 MPa and LHSV of 2 h⁻¹. The dimers selectivity could be significantly improved by effectively controlling the acid capacity of resins via Na⁺ exchange. When the acid capacity of the catalyst was controlled to <2.45 mmol/g, the 2,4,4-trimethylpentenecontent in C8 olefins reached ~100%. It was also confirmed that the sodium exchanged resins have longer lifetime than Amberlyst-15 resins.

这项工作报告了一种新的生产航空汽油的技术方法，该方法是在T = 50°C，P不存在选择性增强成分的情况下，通过在钠交换的Amberlyst-15树脂（20–40目）上异丁烯的催化二聚反应来生产的。 = 2 MPa，LHSV为2 h ^-1。通过有效地通过Na ⁺交换控制树脂的酸容量，可以显着提高二聚体的选择性。当将催化剂的酸容量控制为＜2.45mmol / g时，C 8烯烃中的2,4,4-三甲基戊烯含量达到〜100％。还证实了钠交换树脂比Amberlyst-15树脂具有更长的寿命。
