| 摘要 |
Liquid hydrocarbon feedstocks are hydrotreated in a reactor containing a first catalyst bed and a second catalyst bed by passing the hydrocarbon liquid down through both catalyst beds serially and introducing hydrogen between the two catalyst beds, the hydrogen flowing upwardly through the first catalyst bed and downwardly through the second catalyst bed. The process is useful for desulfurization and aromatic saturation of petroleum and coal-derived liquids.
