摘要
设计了一个根据激光衰减的新方法,用来准确地测量相分离,从而测量有和无功溶剂的汽油-甲醇掺和物的水容忍度。对模型汽油和真实汽油及构成工业总汽油的烷基化油、FCC汽油和重整油等主要炼厂汽油组分的各种掺和物的水容忍度进行了定量。数据的回归分析表明,含有每种助溶剂的掺和物的水容忍度特性可由包括助溶剂浓度、温度和基础油烃类型的关系式来很好地表达。
A new method based on laser attenuation was devised to accurately measure the phase separation and, in turn, the water tolerance of gasoline-methanol blends with and without cosolvents. Water tolerances were quantified for a variety of blends in model and actual gasolines, as well as in major refinery streams——alkylate, FCC gasoline, and reformate that make up commercial gasoline pools. Regression analysis of the data shows that the water tolerance behavior of blends with each cosolvent is well-described by a correlation that includes cosolvent concentration, temperature, and base fuel hydrocarbon type.
