This project will advance the science underpinning technologies for cost-effective use of heavy oil resources. Asphaltene aggregation and precipitation pose enormous challenges for extraction, transport, storage and refining of heavy oils. Understanding the physicochemical properties of asphaltenes is crucial to the future oil industry as light crudes become scarce. This project plans to develop and deploy an innovative molecular probe technique, combined with sequential thermal and solvent extraction and advanced tools for nanoscale characterisation, to reveal the molecular structure and chemical behaviour of asphaltenes. The resulting understanding of the mechanisms of asphaltene aggregation and dissociation may provide a scientific basis for controlling asphaltene precipitation to improve the stability and thus improve the use of heavy oils.

该项目将推进以成本效益为基础的重油资源利用的科学技术。沥青质的聚集和沉淀给重油的开采、运输、储存和精炼带来了巨大的挑战。随着轻质原油变得稀缺，了解沥青质的物理化学性质对未来的石油工业至关重要。该项目计划开发和部署一种创新的分子探针技术，结合顺序热提取和溶剂提取以及先进的纳米级表征工具，以揭示沥青质的分子结构和化学行为。通过对沥青质聚集和解离机理的认识，为控制沥青质沉淀，提高稠油的稳定性，从而提高稠油的利用率提供科学依据。
