Shale oil refining system

Release Time：2020-07-27

Shale oil is a brown, viscous liquid product produced by thermal decomposition of organic matter during oil shale dry distillation.

In the context of the shortage of oil resources, oil shale, as a rich resource, has received more and more attention.

Shale oil generally contains more impurities, which has a great impact on its further processing and utilization.

Hydrogenation, as a very important means of removing impurities and improving product quality in petrochemical production, is undoubtedly the preferred process for processing shale oil.
