摘要:

随着国民经济的快速发展,重油、超重油、页岩油、沥青、油砂等非常规石油资源的开发受到人们的日益关注,且在炼厂所占的比重逐年增加。如何将上述劣质重油资源高效、合理地加工为符合国际标准的清洁燃料,成为国内外炼油工作者研究和关注的重大技术问题。介绍了现有文献中报道的重油流化态热转化提质工艺,如流化焦化、ART、HCC、灵活焦化、双路气化灵活焦化、劣质重油双管快速热解-气化耦合等提质工艺,并对其优缺点进行了分析。同时,对工艺未来发展应关注的研究内容进行了讨论。

Abstract:

As the rapid development of national economy, the increasing attention is paid to the development of unconventional petroleum resources, such as heavy oil, extra-heavy oil, shale oil, bitumen and oil sand. The proportion of unconventional petroleum resources in refinery increases year by year. Thus, how to convert the inferior heavy oil resources into clean fuels conforming to international standards efficiently and reasonably has become a major technical problem. In this paper, a variety of heavy oil fluidization thermal conversion upgrading process reported in the literature were introduced, such as fluid coking, ART, HCC, flexible coking, dual gasification flexible coking, inferior heavy oil double-tube fast pyrolysis-coke gasification coupling process, and so on. The merits and demerits of the fluidization thermal conversion upgrading processes were also analyzed, and the noteworthy research contents about the future development of the processes were also discussed.
