应用于稠油降粘改质中的超分散纳米催化剂的研究进展与前景展望

Research Progress and Development Prospect of Ultradispersed Catalysts For Heavy oil Upgrading

随着常规石油产量的减少,稠油和沥青在世界能源市场上越来越重要了。高粘度稠油和沥青是通过热采产生的,使其流动到表面上,然后使用稀释剂运输稠油进行进一步加工。我们需要多方面的努力达到既能够改善热采方法同时又能够提高采收率和产物质量。详细评述了近年来超分散纳米催化剂的研究进展,流动能力,改质降粘程度以及对其采收率和环境的影响。

Heavy oil and bitumen are playing increasingly important role in the world＇s energy market with the decline of conventional oil production. High viscosity heavy oil and bitumen are produced by thermal recovery mechanisms, and then diluent is used to transport heavy oils for further upgrading processes. There exist extensive efforts to improve the thermal methods with both recovery and quality enhancement simultaneously. In this paper, the ultradispersed catalyst in the recent years was reviewed from the aspects of research progress, flow capacity, the degree of viscosity reduction and the effect of the oil recovery and environment.
