摘要/Abstract

摘要： 为深入认识固定床渣油加氢-催化裂化双向组合技术溶剂芳香性与沥青质稳定性的关系，采用Flory-Huggins模型考察了沙特轻质原油常压渣油的沥青质稳定性，并用溶解度参数关联了溶剂的芳香性。结果表明，Flory-Huggins模型可用于研究渣油体系的沥青质稳定性。随着溶剂芳香性的增加，其溶解度参数增大，沥青质稳定性增强。密度较大、H/C原子比较小的溶剂具有较大的溶解度参数，对沥青质的稳定性较有利。

关键词: 溶解度参数, 芳香性, Flory-Huggins模型, 沥青质稳定性

Abstract: The relationship of solvent aromaticity and asphaltene stability of Saudi light AR in RICP technology was studied by Flory-Huggins model and the aromaticity of the solvent was correlated with the solubility parameter. The results proved the availability of Flory-Huggins model for measuring asphaltene stability in residue. The aspaltene stability increased with the increase of solvent/AR ratio. The aromaticity could be evaluated by solubility parameter. The solvent with higher density and lower molar ratio of H/C possessed higher solubility parameter and is beneficial to asphaltene stability.

Key words: solubility parameter, aromaticity, Flory-Huggins model, asphaltene stability.
