摘要
研究了离子液体对稠油黏度、组成和平均分子量的影响。结果表明,离子液体对稠油具有较好的改质降黏作用。稠油经离子液体处理后,其饱和烃、芳香烃、胶质质量分数增加,沥青质质量分数明显下降,从而导致稠油的黏度降低,平均分子量减小。研究结果还表明,过渡金属盐改性离子液体对稠油的改质具有催化作用。
The effects of ionic heavy oils are investigated. The y oils. After reaction with ionic liquids on viscosity, hydrocarbon composition and average molecular weight of results indicate that ionic liquids have good viscosity reduction property for heavliquids, the amount of saturates, aromatics and resins increase, while asphaltene decreased. This leads to average molecular weight and viscosity of heavy oil decreased. The results also indicate that metal ion modified ionic liquids have catalytic effect on the upgrading reaction of heavy oils.
