| 中文摘要: |
| 以桦甸油页岩为研究对象,采用逐级提取实验,考察了不同升温速率及干馏终温,其内部赋存的Cr、Co、Pb、Cu、V五种微量元素的形态变迁特性。研究结果发现：各元素均在2.5℃/min和20℃/min表现出了较大的迁移率,且干馏终温越高更有利于元素的迁移；低升温速率和高干馏终温更能促进元素大部分形态的迁移,但硫化物结合态的迁移在高升温速率和高干馏终温则更为有利；元素不同形态的迁移总会有一部分向有机物结合态转变。 |
| 英文摘要: |
| States transformation of trace element Cr、Co、Pb、Cu、V in Huadian oil shale during retorting were be studied. The retorting experiments were conducted at different heating rate and retorting temperament. The experiment was used the method of sequential chemical extraction (SEC). The results indicate that trace elements have a higher migration rate in 2.5℃/min and 20℃/min,and the higher retorting temperature, the better trace elements migration. Most of states transformation are better migration with low heating rate and high final temperature, but sulfide bound fraction is better migration with high heating rate and high final temperature. Different states will have some parts migrate to organic matter bound fraction. |
