超临界水中基于重芳烃自组装的重质油脱金属

摘要

In supercritical water environment,heavy quality demetal experiments have been carried out.The experimental results show that heavy oil cracking is transferred from oil phase to supercritical water phase in the environment of high water to oil ratio and high solid density.Compared with cracking in the oil phase,heavy oil can accelerate the rate of cracking in supercritical water environment and is affected by hydrothermal conditions.%在超临界水的环境中重质油脱金属的实验,实验结果表明,在水油比和实密度较高的环境下,重质油裂化从油相转移到超临界水相的过程中.相较于在油相中的裂化,在超临界水的环境中,重质油能够加快裂化的速率,并且受到水热条件的影响.
