A good binary solvent for asphaltene was identified using Hansen solubility parameter (HSP) analysis, and aggregation behaviors were determined by small-angle X-ray scattering (SAXS) measurements. The pure solvents showed poor performance in dissolving asphaltene, whereas a mixed solvent system of 83 vol% benzyl benzoate and 17 vol% hexane dissolved up to ~16 wt% asphaltene. SAXS profiles at 10,000 mg/L of asphaltene in the binary solvent showed disappearance of nanoaggregates. These findings will be useful when developing mechanisms for controlling asphaltene aggregation/disaggregation in the crude oil industry.
期刊介绍：
“Journal of the Japan Petroleum Institute”publishes articles on petroleum exploration, petroleum
refining, petrochemicals and relevant subjects (such as natural gas, coal and so on). Papers published in this journal are
also put out as the electronic journal editions on the web.
Topics may range from fundamentals to applications. The latter may deal with a variety of subjects, such as: case studies in the development of oil fields, design and operational data of industrial processes, performances of commercial products and others
