摘　　要：水在超/近临界状态下具有黏度低、扩散系数大,且能够与油等大多数有机物互溶的特点。综述了超/近临界水在重油加工方面的应用情况,重点分析了其对脱硫、脱氮、生焦量及产品性质等的影响。指出超/近临界水作为一种新型绿色溶剂,在重油加工领域具有广阔的应用前景。Supercritical/subcritical water exhibi- ted a lower viscosity, a higher diffusion coefficient and miscibility with many organic compounds, such as oil. The application of supercritical/subcritical water in residue processing was reviewed and the in- fluence of supercritical/subcritical water on desulfu- rization, denitrogenation, coke yield as well as the performance products was summarized in detail with 23 references. It was pointed out that the supercriti- cal/subcritical water,as a novel green solvent, had a bright prospect in heavy oil processing.
